These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Blacklist
Anticlimax Boss: In-Universe: Reddington has been on the FBI's Most Wanted list for decades, yet he surrenders himself without a fight.
In "Anslo Garrick", it's revealed that Red is personally this to Ressler, since he spent years unsuccessfully hunting him, even ending a relationship in the process.
Broken Base: Liz Keen and her actor Megan Boone is the major one among fans. A strong, sensitive character or an incredibly incompetent, hysterical weak fool who only gets by courtesy of Reddington? As for Megan Boone, a significant portion of the fanbase consider her inexperienced, wooden and hopelessly out-matched by the more experienced James Spader while a growing number believe she is settling into the role.
Butt Monkey: The FBI Task-Force as a whole. Massive casualties, constantly being outfoxed without the aid of the criminal mastermind they're consulting and being manipulated by said criminal mastermind for their own ends. It's a miracle that the Bureau hasn't shut them down yet.
"La Grange" is used when Reddington's child soldier abductors take out a pursuing Humvee in the forests of Cameroon.
"You Were Born" is used in the end of "The Front" while Reddington watches an old film reel of his family, which gave him the inspiration to track down his missing daughter.
Character Shilling: Lizzy suffers from a horrendous case of this. Season 1 has her being played up as "special" and "gifted" by Red and her profile but spends much of the time being Reddington's plaything and being highly incompetent without his help. On the other hand, other portions of the fan-base dispute this, point out she's a Na´ve Newcomer and stress the fact that the events she goes through are quite a lot to take in for someone who is only a month out of the FBI Academy.
Season 2 makes this come back with a vengeance. Liz seemingly grows a spine and tries to do something useful sucking out whatever information Tom has on Berlin and also starts to put the pressure on Red. However episode 8 has The Reveal demonstrating she's once again been manipulated by both Red and Tom, the latter who she lets off scot free and is reduced to a emotional wreck due to her inability to make a decision on whether to shoot him, this smashing what was supposed to be character development.
Fan Disservice: As of episode 8 of season 2, the Blackist has had three male blacklisters that like to strip naked. Normally this would be Fanservice if not for the fact that all three are wrinkled old man, one was covered with scars from acid burns, one doesn't have a nose and one was a Psychotic Man Child whose hobby was making human dolls.
Fanservice: Fake Keen stripped down to her panties to tease/troll Ezra through the window certainly counts.
As does Real Keen spending much of "The Scimitar" without any pants on, giving the audience a nice view of black panties.
Ressler has been known to get his shirt off at times.
Fridge Horror: Liz successfully captures "Lord Baltimore" a.k.a. Nora Mills. Yay! Except, the "Rowan" personality still exists inside Nora and. as Liz points out, the two personalities weren't aware of each other and therefore could not have been conspiring to cover up Nora's crimes. That means that Rowan is basically an innocent victim of Nora's criminal empire. Now consider that anything could potentially wake up the "Rowan" personality: She could find herself in a federal prison, having no clue why she's there and completely at the mercy of her fellow prisoners. (Since Rowan, unike Nora, is not a hardened criminal).
Hilarious in Hindsight: A meta example. In "General Ludd", William Sadler plays a dying man who's confined to a hospital bed. Then, on the Elementary episode "Blood Is Thicker", which was broadcast three days later, Sadler played... a dying man who's confined to a hospital bed.note Technically, the Elementary character wasn't actually hospitalized, but the comparison still fits.
Idiot Ball: The FBI grab it constantly and have to be helped along during episodes by Reddington's intervention.
Just Here for Godzilla: James Spader's performance as Raymond Reddington is widely touted by fans and critics as a major highlight and one of the only things holding the show together.
Magnificent Bastard: Like him or hate him, Reddington always shows a sense of style and grace, the calm master criminal vs. the often overworked and harassed FBI agents.
There's also Madeline Pratt, who's able to play Reddington himself as part of her own schemes though he gets her back.
Berlin in spades constantly on his guard when Red is around and immediately tracks down one of the things Red cares about, the latter's wife. But like Pratt, Red gets him back by throwing him off his game through revealing his daughter was alive and later shooting him dead after both men have consumed a large quantity of vodka
In "Dr. Linus Creel", Keen and Ressler track down a creepy Psycho Psychologist who goes about deliberately sabotaging people's entire lives as part of sick experiment. And the creepiest part is, it's all funded by The Government. It doesn't help that many people believe the idea that The Government caused the spike in mass shootings as a way to justify their stronger laws on gun control.
The whole situation with Lord Baltimore is something that could theoretically happen to anyone under the right circumstances. You could very well be a Split Personality being used as a cover by a criminal-for-hire and you would have no way of knowing. Have fun with that idea.
The Scrappy: Tom and Elizabeth Keen along with the FBI task-force. A portion of the fan-base immensely dislikes the plots regarding the Keen's domestic troubles having claimed that they are a side-show which distracts from the main plot featuring Reddington. As for the FBI task-force criticism was directed at how some of the characters were under-used or boring in comparison to Red. Agent Ressler in particular gets this due to his Jerk Ass tendencies.
Megan Boone's performance as Liz Keen is a massive sticking point. A significant portion of the fan-base believes she's a inexperienced, wooden actor who does not match the formidable James Spader during their scenes together while the other section disagrees and thinks she needs more time to settle into the role.
Ship Tease: Aram & Samar near the end of "The Front".
Special Effect Failure: Any time there's Stuff Blowing Up (and since this is an crime action-drama, that happens quite a lot), the CGI is painfully bad. Case in point: the plane bombing at the start of "General Ludd."
Three words: Megan Boone's wig. It was subject to much mockery during the first season (including one poll on whether it should have its own credit) and was ditched after the season two opener when Boone was able to switch to her own hair.
Spoiled by the Format: Somewhat averted with this show's use of two-parters with a single Blacklist Name - despite the Antagonist Title, the show avoids using "Part 1" and "Part 2" to differentiate multi-parters, which are instead titled normally for the first episode (eg: "[Insert Name] ([Insert #]); after the episode ends on a cliffhanger however, the 2nd part uses "Conclusion" in place of the number. This enabled the show to surprise people when "Anslo Garrick" took two episodes to resolve (despite being a Mid Season Finale, it was still something that hadn't been done before on the show), and would help the writers if, in the future, they pulled another two-parter for a villain at an unexpected time in any future season).
They Wasted a Perfectly Good Character: Some people felt like this in relation to Anslo Garrick, who was quite an interesting and fearsome antagonist killed way too early. Subverted, however, with Berlin (the first blacklist name who was still loose after his Antagonist Title episode ended), and also with Fitch, in hindsight - he dies in his title episode, but we didn't know he was on the Blacklist - thus, his Arc got some decent mileage and development, building it up until its intended conclusion.
One episode featured beloved character actor William Sadler as Liz's adoptive father, but he died in that same episode. There is always the possibility of flashback though.
Reddington's associate Grey was killed off midway through Season 1 after a revelation that he was (unwillingly) serving as The Mole to Red's enemies
Unintentionally Unsympathetic: Liz. Sure she gets dragged into a world which she has no experience in surviving but portions of the fan-base loathe her due to her perceived incompetence, emotional nature which causes her major mistakes and the fact she constantly gets played for a fool by Reddington despite attempts to play up her status and skills can be rather grating to some viewers. Also, her seemingly constant reliance on a male character to function whether on the job or in her personal life has made the portion of the fan-base which dislikes her consider her a weak character.
Liz also falls into the Designated Protagonist Syndrome (though arguably she's more the Deuteragonist to Reddington) that is inevitable with an Audience Surrogate in this kind of setting. Not only is she overshadowed by a more compelling co-starring character and more entertaining supporting cast - which makes her characterisation somewhat bland in comparison - but she is The Heart because she's intended to be a humanising character to contrast with the amoral Reddington and more jaded Task Force in order to avert Darkness-Induced Audience Apathy - she's there to be connected to. The problem with this is that in a setting which depends on the protagonists being Good Is Not Nice/Good Is Not Soft at the least, she isn't allowed to grow out of her vulnerability and kind-heartedness, which also overshadow the Informed Attribute that are her darker traits (mentioned way back in the pilot). She is arguably a necessary character as she is, but the question is whether they could (or should) change her in a manner which the fanbase would desire, or whether that would defeat the purpose of her role in the story (ideally, the writers would Take a Third Option with this).
