After finishing the entire Twilight series, he didn't want the books in his house anymore, but thought destroying them would send the wrong message. So he filmed himself hiding them all over Los Angeles, with notes inside for anyone who found them directing them to his site. Unfortunately, he has yet to receive any word if this paid off.
The Sozin's Comet liveblog—old and new fans alike turned up in droves, breaking the site and surpassing the A Very Potter Musical liveblog as the most-commented event yet.
His liveblog of Half-Blood Prince on Buzznet received over seven thousand comments. (Compared to three thousand for Sozin's Comet)
And that record was smashed into oblivion by the liveblogs of the Lord of the Rings films.
Garnering praise from Neil Gaiman himself while reviewing American Gods.
A direct quote from Mr. Gaiman: "I enjoyed your American Gods read so much. It was like getting to look through a reader's eyes & find out what worked."
The Buffy the Vampire Slayer fans crashing the site within one minute of the pilot review being posted. Mark was quickly forced to find a new server so this wouldn't happen every single day.
The final chapter of his Breaking Dawn LB, where Bella, Edward, and Jacob get fed up with the way they're written and deliver an epic "The Reason You Suck" Speech to Stephanie Meyer. Then they're prepared to kill her as fully in keeping with the characterization she gave them, but are stopped by Renesmee, who points out that whatever Meyer made them do before, they clearly have their own free will now, and can choose to be the bigger people. So they just leave her to wallow in her own shame as she weakly apologizes.
J. August Richards Tweeting that Gunn will marry him.
His response to The Great Spuffy Meltdown of 2012, furiously laying down the law before his review of the Angel episode "Dad" and the Buffy episode "Gone."
The end of his first playthrough of Dragon Age: Origins. He killed the Archdemon on his first try, with the whole party dead except Alistair, no health poultices left, and Alistair down to a tiny amount of health by the time he made the final blow. And right at the time his hour was up!
He spends most of the video for the Friday Night Lights pilot talking about how he's never cared about football, and his high school had a crappy team anyway. But from the moment Matt steps into the quarterback spot, he becomes indistinguishable from the in-universe fans watching the game, cringing at the bad plays and cheering for the good ones.
Getting nominated for a Hugo alongside one of the very books he was currently reviewing.
His furious deconstruction of Lord Wyldon's arguments for why women shouldn't be knights in Protector of the Small.
And then his joy at seeing Wyldon change into a man who respects and trusts Kel.
Dealing with an unbelievably poorly translated line in Fullmetal Alchemist: Brotherhood that made Ed look like a racist. What followed was a very mature discussion about the original Japanese line and the various ways it's been translated, how some are much better than others, and how the dub translation was the worst choice they could possibly have run with.
When he announced he was doing Supernatural, he said he'd just give the first season a shot, and stop if it hadn't grabbed him given the problematic things he'd heard about the show. Then when he actually got to it, he announced that he would be doing the whole thing (with the show still ongoing and about to begin its ninth season) just to spite the people who insulted him for watching it in the first place. He finished by saying that even if he ends up hating it, it will still be fun to write about as a return to his Twilight days.
In Chapter 15 of Untold, his response to being accused of only saying he likes the book because he knows the author is reading his reviews.
And when he was very nervous about tying in detailed stories of his own life while reviewing the book, to a much greater degree than ever before, Gaiman replied that it was the perfect way to review it.
His reaction to the Mighty Whitey aspects of Daughter of the Lioness, showing that he's not going to let this kind of thing slide, even from one of his favorite authors who is also a commenter on the site. And once again, the other commenters provide a completely mature and thoughtful debate on the subject, with none of the childishness you'll see anywhere else on the Internet where these subjects are discussed.
Providing impromptu accompaniment to the first instance of "Carry On, Wayward Son" in Supernatural.
And for the season 5 finale, a fan tweeted about the song literally the second he started watching.
For someone who is so often blindsided by plot twists, he figured out the America the Beautiful clues in The Westing Game very quickly.
And the theme naming, though he didn't guess what it meant.
Taking eight fans to see the Veronica Mars movie on opening night, for free. And he said any other fans in the area were welcome to come too.
He again shows he's not going to let problematic stuff go even in works he loves when he takes Veronica Mars to task more and more for the Straw Feminists in season 3.
While watching The Middleman he's exactly in tune with Wendy Watson, to a kind of scary level. The highlight is when they say "Sweet" at the exact same time when the Middleman brings up ghosts.
His review of episode 2x4 of Hannibal, which is entirely a rant about Beverly being Stuffed into the Fridge, both what a bad story decision it is and how insulting to women and Asians it is.
During the Star Trek episode "The Menagerie Part II," he raises his hand when it's said that no man can resist an Orion slave girl.
The review of "Patterns of Force." His horrified disgust with the episode just radiates off the screen.
Ditto "The Omega Glory."
In "The Paradise Syndrome" even the video is full of it, calling out one horrific piece of Unfortunate Implications after another and ending up declaring it the show's new low point.
Immediately catching the subtle change of transporter coordinates in "The Mark of Gideon."
The furious condemnation of Dean erasing himself from Lisa and Ben's memories without their consent in Supernatural.
The review of "Man's Best Friend with Benefits," where he seriously suspects the episode is from some alternate universe as the only way it could be written, filmed, and edited without anyone ever realizing how horribly offensive it is.
The rant against the show killing off Kevin Tran, and how it's an undeniable part of a pattern of the show's crappy treatment of non-white male characters.
Nailing his first prediction for Season 10, that Dean would be cured in three episodes.
His Twitter post upon watching "Dark Dynasty": "I talk a lot of shit, y'all. I know it. And most of the time, it's out of like… respect and love and wanting better things. I have never meant the following sentence more in my entire life, but seriously: Fuck you, Supernatural."
The review of Wyrd Sisters Part 13 features a quite thorough rebuttal to the people who constantly accuse him of being a Social Justice Warrior. He's not condemning older works like this for not conforming exactly to modern senses of political correctness, just pointing out that these things can be a problem and writers shouldn't do them. Plus, that very same day also saw his review of "Patterns of Force" noted above, showing that no matter the era, some ideas are just so wrongheaded that even at the time the writer should have known better.
Some of Mark's predictions can fall into this when he gets something right, but one of the best has to be predicting that Ty Lee would betray Azula in book three of Avatar: The Last Airbender. Fans who'd already finished book three exploded over on the spoiler site.
After he naturally threw a fit on Twitter after watching The Wrath of Khan, a fan provided the perfect rejoinder: "Sorry, but the needs of the many outweigh the needs of the one."
Many times while reading Fifty Shades of Grey, he pauses to explain exactly why Christian Grey is such a monster while still showing complete respect for BDSM lifestyles and acknowledging he has little personal knowledge of it.
His review of "Code of Honor" from Star Trek: The Next Generation is more of a treatise on how to avoid the racism and sexism that the episode reeks of, while also slinging plenty of deserved jabs at the more basic script problems.
He naturally goes completely medieval on "The Outcast," accusing Jeri Taylor and the others involved of being a bunch of cowards who wanted to pay lip service to the idea of homosexual/transgender equality without any real understanding of the issues involved, let alone any willingness to portray them without a heavy protective cloak of allegory to pander to all the bigots watching the show.
His "The Reason You Suck" Speech to "Journey's End" for its ill-conceived portrayal of Native American culture, at the writers for acknowledging the Unfortunate Implications in the episode and then ignoring them, and at the Traveler in particular for using Native American spirituality and culture to better himself then sanctimoniously leaving them to die by claiming he was above their troubles now, because of the power that he stole from them.
The articles on Moving Pictures are very much informed from his own experience living in Los Angeles, and give a fascinating insight into how deep the book's satire goes.
Not only Mark himself but several commenters giving the show hell for all the Unfortunate Implications in it, despite their generally liking it.
In the video for the series finale, he looks forward to finally learning what this big thing that broke the Internet was and that his fans have been dutifully shielding him from learning. This includes one guy who maliciously tried to spoil him, which everyone else put a stop to by throwing things at the jerk.
His appearance at ConQuesT 46, sharing the stage with George R.R. Martin and Brandon Sanderson.
The Tranquil Fury of his review of the Supernatual episode "Dark Dynasty," coldly tearing apart why killing Charlie was a horrible, insulting story choice, finishing it by saying that he would stop watching the show if he wasn’t obligated to continue watching it.
After realizing he was reaching the end of his list of future shows to watch, he reopened the poll to find more. Thing is, this was several months after the premiere of Sense8, a show absolutely tailor-made for him with its incredibly diverse cast, heavy focus on non-heteronormative issues, and fascinating sci-fi premise on top of it. And even without giving away a single thing of what the show actually is thanks to his strict spoiler policy, the response that he should watch the show was so overwhelming that he not only added it to the list but bumped it up to be the very next show on his schedule.
His method of talking about the death of Wells in The 100, talking about it entirely in terms of what a bad story decision it was, setting up this character with a ton of good backstory and promise for future developments just to kill him off as a cheap shock tactic, then throwing in at the end that the racist implications of this happening to a black guy are so obvious that he doesn't even need to explain them.
And yet, after this extremely rocky start, he ended up absolutely adoring the show, calling it one of the most relentlessly paced and constantly fucked up things he'd ever seen, and even perhaps the most fun he's ever had making videos for the site.
Much like Legend of Korra, he managed to remain completely unspoiled about some issues in Season 3 that are right up his alley, enough that several times since the episodes aired he's had people make clear they want him to discuss something about it, until he moved the season up to be the next Double Feature just to make sure he wouldn't get any spoilers. Making it more impressive is that Baize clearly does know about Lexa's death and spends every episode wondering when it's going to happen.
The creators of Star Trek: Deep Space Nine deliberately put the first mention of the show's Big Bad the Dominion into a filler comedy episode so people would dismiss it until it came back with a vengeance later. And then the guy who's perpetually surprised for a living picks up on it right away, insisting that it has to be important somehow.
In his Season 3 prediction post for Deep Space Nine, he manages to get every single prediction right, with only one exception: thinking that Bareil and Winn will appear in three episodes each this season, when they only appear in two each. Easily his best prediction post yet.
Within a couple hours of his making a Twitter post raving about "The Visitor," where Tony Todd played the adult Jake Sisko, Todd subscribed to him.
His deconstruction of Silaran's reasoning in "The Darkness and the Light", utterly denouncing the idea that he was a victim by pointing that even if all he did was fold shirts, he still willingly participated in the colonization of Bajor and and knowingly benefited from the horrific oppression of the Bajorans.
His review of "Far Beyond the Stars," where his praise of the episode directly tackling heavy social issues without the sci-fi genre's usual allegory shield (see the above entry on the TNG episode "The Outcast") is intercut with several stories of the racism he's faced to stunningly powerful effect.
He ends up declaring Deep Space Nine not only his favorite Star Trek series, but the home of his picks for the three best episodes of the entire franchise in "The Visitor," "Far Beyond the Stars," and "In the Pale Moonlight."
His Death Note reviews are pretty much a constant barrage of deconstructions of Light's actions and motivations, providing a great thing to point the series' notorious Misaimed Fandom to and say "That's why Light is the bad guy."
The Facebook post about the hell he went through at ConQuest, which quickly went viral and resulted in nigh-universal condemnation of the con. Shortly afterward, one of the people who refused to do anything about the harassment resigned from the staff of another con, and sent him one of the few apologies he got from it (which he was perfectly fine with, having never actually asked for anything in the post).
The entirety of Interesting Times, taking a wrecking ball to its horrific racism, which reached such heights in this book that even many huge Pratchett fans prefer to forget it exists (and had some of Mark's fans seriously worried that it would cause him to quit the series altogether). Keep in mind that he's having the guts here to take on the faults of a writer who's not only highly beloved but recently deceased.
Despite knowing nothing about the behind-the-scenes issues that plagued Star Trek: Voyager, in "Non Sequitor" he was able to pick up that Garret Wang had been deliberately directed to constantly play Harry Kim as nothing but a wide-eyed waif, refused any kind of character development.
In "Worst Case Scenario" he initially dismisses Tuvok as the mutiny story's author, but then walks back on it shortly before the reveal, and even correctly guesses that it's actually a training scenario.
Though it takes him a while to place her name, he immediately recognizes Jeri Ryan under the heavy Borg makeup, despite having no idea she'd be showing up.
After having a great deal of problems figuring things out in "Men at Arms", he figures out the method of poisoning in "Feet of Clay" a full two parts before Vimes does.
An avid player of Pokémon Go, during a con appearance in Amarillo, Texas he took over every single gym in the area during his time off. His chaperone joked on Twitter that future people with the job should know this is what happens if you take your eye off him.
After upgrading his servers due to the above influx of Buffy fans, it was smooth sailing for a few years...until his article on the Steven Universe episode "Jail Break" overwhelmed even that setup. And along with that was an amazing bit from Mark himself on how the episode is a proud declaration of queerness, and he's proud to be part of it.
He got so invested while reading Jingo that he actually read the word "bitch," something he usually never actually says out loud, instead pausing and saying "that word" whenever he comes across it.
