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.

YMMV: Epic Rap Battles of History
Acceptable Targets: Adolf Hitler is the only character to have something horrible happen to him at the end of the video. Three times. Whether or not you think he raps better than Vader, he's Adolf Hitler and Vader is allowed to kill him at the end of every video because he's that evil.
Alternative Character Interpretation: Most of the rappers' personalities are exaggerated from what history remembers, or canon in the case of fictional characters. Example, Bieber is depicted as an annoying, pint-sized brat, but more likely than not, the real Bieber is not as annoying (some of the time). Mister Rogers was normally a friendly man, but here, he's a perpetually placid fellow with a short fuse.
Awesome Music: The series has a number of epic beats. Matches that stand out include:
Any "Darth Vader vs. Adolf Hitler" match. The first has a significant improvement in musical and lyrical quality over "John Lennon vs. Bill O'Reilly", the second has the soundtrack of Van Helsing as its background music, and the third has some particularly memorable lyrics.
"Abraham Lincoln vs. Chuck Norris".
"Ludwig Van Beethoven vs. Justin Bieber".
"Albert Einstein vs. Stephen Hawking".
"Genghis Khan vs The Easter Bunny."
"Napoleon Dynamite vs. Napoleon Bonaparte".
"Dr. Seuss VS William Shakespeare" has Shakespeare's second verse, which leaves the Cat In The Hat dumbfounded and impressed. That's not to say that the Cat In The Hat was a slouch, either.
Batman vs. Sherlock Holmes is possibly the most polarizing episode yet. Half the fans like it just fine, the other half found Batman's delivery of his verses to be off-putting, on top of Batman having very few good lines.
Some comments in the Gandhi VS MLK battle suggest that more than a few people didn't find the portrayal of either all that honorable towards the men.
Adam vs Eve, for not being about Adam and Eve so much as a rap battle between Man and Woman. Also, it's arguably the most raunchy of the battles.
There's also a division between the fans that want to see more matches between Adolf Hitler and Darth Vader and fans who think that the battles between the two are getting stale and the focus of the show should be placed elsewhere. The latter was acknowledged in "Hitler vs. Vader 3" in the form of an included comment.
Reception to Miley Cyrus vs Joan of Arc has proved to be pretty divided so far: while some people are fine with it, it has a share of detractors who think it's one of the worst battles. There are also fans who are disappointed at the match-up and wish Joan had gotten a different opponent.
Crack is Cheaper: Bill Gates says that people can still afford to get medical help if they buy a PC over a Mac.
Boba Fett. He only appears for eight seconds and gets killed by Hitler of all people, but his lines were so awesome that he's become very popular, with people pleading for him to return. Interestingly enough, he was voiced by Ray William Johnson, a particularly divisive YouTube personality, which shows how much people liked the character.
Nikola Tesla. His battle with Thomas Edison was one of the most requested rap battles up until they fought. He also is one of the few battlers to be overwhelmingly considered by fans to have curb stomped his opponent.
Edward Kenway. His cameo in Blackbeard vs. Al Capone was so popular, there is a huge, increasing number of fans begging for him to have his own battle.
Happens constantly during "Einstein vs. Hawking", obviously. For example, p-brane (pronounced the same as pea-brain) is a vital element in string theory. Also, 'relatively blown' refers to Einstein's best known theory (relativity).
The entirety of Shakespeare's first verse is in iambic pentameter. Minds will be blown.
Not only that, but it's complete with Ye Olde Englishe phrases, pronunciation and theatrical gestures.
Said to the Wright Brothers: "You might fly like a hawk, but you fight like a kitty!"
Bill Gates VS Steve Jobs is full of tech-based jokes.
There's a delicious double pun in the line "I think different from the engine of the days of old" - simultaneously playing on Apple's old slogan and Charles Babbage's original computer.
Mozart vs. Skrillex is full of awesome music in-jokes—musical terms relevant both to composition and synthesizers, references to several famous electronic musicians, and even a reference to Mozart's tendencies to wax scatological.
Vader off-handedly referring to the Stormtrooper clones being superior to Hitler's.
Understanding "Rasputin vs. Stalin" requires quite a bit of knowledge on Russian history.
Joseph Stalin's right hand was reportedly withered, which is directly referenced by Lenin.
Stalin's boast about taking Leon Trotsky "out of the picture" is both literal and figurative, as Stalin orchestrated Trotsky's exile (and possibly assassination), and later altered photographs to remove Trotsky from Lenin's side.
Gandhi's advice telling MLK 'With protests and women the same advice goes, always stay away from the ho's' isn't just a fun play on the word 'hose,' which MLK's followers got hit with a lot in protests, but also a reference to the lesser-known allegations of adultery often leveled at him.
"My technique will make your mistress weep / put her to sleep, elbow drop a dream, I go deep" is an extended reference to Picasso's "The Dream". Dora Maar, Picasso's mistress, posed for the painting, and it tore a bit when someone pushed his elbow into it.
The two kids Kanye West ends his verse with in "Donald Trump vs. Ebenezer Scrooge" aren't random homeless children, they're Ignorance and Want, two children who serve the same function in the original Dickens novella.
Hate Dumb: A few people disliked the season 2 finale because they couldn't recognize who the contestants were Despite everyone but Gorbachev being name-dropped.
Darth Vader tells Hitler (played by Lloyd) that he has a Napoleon dick. Guess who Lloyd plays in a later video?
In the same video, Vader moonwalks. He was played by NicePeter, as was the adult Michael Jackson in season two.
In the rematch, Vader comments that he's "on the leader of your limp-dicked Luftwaffe" before making a reference to Lucas's other famous production, Indiana Jones. Then another Lucas production about pilots taking down the Luftwaffe came out.
Lady Gaga makes a reference to the Jackson 5. 15 episodes later, The King of Pop himself (with a short appearance by his sibs) takes a shot at the mic. Both Gaga and Adult!MJ are played by Nice Peter to boot.
Speaking of which, what about in Battle 6 when Justin Bieber says he's the next Michael Jackson? Or Genghis Khan telling the Easter Bunny that he's about to feel Wrath of Khan before Captain Kirk rapped?
Two examples of this come to mind. First of all, in the Einstein vs. Stephen Hawking battle, the lyric "I'm the Snoop Dogg of science" is funny considering that Snoop Dogg ended up appearing as Moses in a later episode. Another example lies in the lyric, "Call me Arthur Miller, son..." from Ben Franklin vs. Billy Mays, which is funny considering the wife of Arthur Miller, Marilyn Monroe, would appear as a rapping contestant later on.
In the trailer for Season 2 at the end of Episode 15, a quote from Vladimir Putin appears, saying he will kill Nice Peter if Season 2 does not have a Russian character. The Season 2 finale has five Russian characters, of which one is Putin.
Most Annoying Sound: A bizarre example as it doesn't come from the Epic Rap Battles at all. After "Bill Gates vs Steve Jobs" battle came out, many fans went looking for an instrumental version of the beat used, only to quickly grow tired of the original's use of "Tristan on the track" as a refrain. Tellingly, numerous versions now exist on youtube, editing it out.
Darth Vader in the rematch when he removes his helmet.
HAL 9000 intrudes on the battle between Bill Gates and Steve Jobs. He's appropriately eerie, boasting of his superiority in that infamous monotone of his. The most terrifying thing about him is that he does not seem to move on his own, nor does he emote.
After Steve Jobs dies in his battle with Bill Gates, Gates seems to go insane, especially compared to his previous Tranquil Fury... just look at his last verse:
Now there's no one that can stop me! THE WORLD IS MINE!
The especially creepy part is how he seems to realize this mid-verse, going from yelling at Steve's death to "I'm alone now, with nothing but power and time...and no one on Earth who can challenge my mind!" His sudden change is frightening.
Skrillex briefly turns into a "Scary Monster" that looks kind of creepy.
Stalin's portrayal is quite...unsettling. Most of his lines are part of a long, thorough death threat towards Rasputin and everyone he knows. What makes this worse was that he wasn't any better in Real Life.
Thing 1 and Thing 2's high pitched voices, creepy look and Ax-Crazy lines make them scary.
The Ghost of Christmas Yet To Come is as dark and creepy as he is in the book, albeit averting The Voiceless in favour of Evil Sounds Deep (or rather morally ambiguous). He's not once played for laughs either, and there's only a second's indication that he'll turn up. Nice Peter even invokes this in the Behind the Scenes video.
"Boo! You're gonna die, with no one to love you and no one to cry!
Older Than They Think: There's a small group who considers Rhett & Link's Epic Rap Battles to be ripoffs of these; their first Epic Rap Battle (the stright-up match between the two) predates John Lennon Vs Bill O Reilly.note Nevermind that the two pairs are on pretty good terms with eachother, and that Rhett and Link appeared in Mario Brothers Vs Wright Brothers while Peter and Lloyd made a cameo in R&L's Epic Rap Battle of Manliness.
One-Scene Wonder: Boba Fett appears for all of maybe eight seconds in the season 3 premiere. The half-verse that he does manage to get is awesome.
Painful Rhyme: Being based on rap, this was unfortunately inevitable.
"Look at these two, their lives must've been horrible / Two dorky dudes named Wilbur and Or-i-ville"
Rhyming "streets" with "mysteries" in Batman vs. Sherlock Holmes.
Einstein rhyming "serious" with "theory was"
Lenin rhymes 'Right hand man' with... 'Right hand, man.' The context it's used in is clever, but it's still unpleasant to the ear.
Edison rhymes "gently" with "directly".
"Whose rap flow's the dopest? Marilyn Monroe's is"
Not a painful rhyme but, due to where he puts the emphases, Blackbeard's line "You're an obese greasy sleaze squeezing a diseased peter" definitely doesn't flow as well as it could.
The last six lines of Rasputin's verse respectively end with: "mind," "price," "lives," "Kryptonite," "hypnotize," and "wife."
Muhammed Ali turning "wobblin'" and "goblin" into three-syllable words.
Rooting for the Empire: In the second Hitler vs Darth Vader battle, many people like Hitler better, even though he's definitely the more evil of the two. Of course, if you're on Vader's side, you're still rooting for the empire anyway.
Thing One and Thing Two aren't popular with the general public.
Thomas Edison got only ~15% of the votes on the official page. Just like Bieber's case, this was probably an Intended Audience Reaction.
Win Back The Crowd: The fandom was displeased with the unannounced hiatus that happened after the Bill Gates VS Steve Jobs, some even going so far as to thinking that the work would become an Orphaned Series. Cue the announcement that the next six Rap Battles would be uploaded back-to-back every fortnight, followed by a holiday break and more episodes. This was impeded only by a small Schedule Slip in regards to Batman VS Sherlock Holmes.
The Easter Bunny really bit off more than he could chew.
Freddie Mercury starts off as one. He spends most of Frank Sinatra's first verse and part of his first verse moping at his piano. Then he gets going.
Iron Woobie: It's subtle, but Vladimir Lenin apparently watched his most trusted student dismantle his efforts toward a socialist paradise in favor of a brutal dictatorship. The reason you don't notice is that Lenin vents about this with authority.
Writer on Board: While most battles have all participants nail a few key blows against their opponents, or have a weak start with a killer Wham Line finish, others are so lop-sided (or have a special guest who acts as a mouthpiece) that it's clear the writers heavily favor one side. While nobody's going to dispute who should win in Genghis Khan vs. the Easter Bunny, the slant in other episodes has led to some Internet Backdraft against fans who take exception.
