History YMMV / IAmLegend

* TheWoobie: Neville, being lonely and undergoing a SanitySlippage, ultimately attempting suicide when he loses [[spoiler:Sam.]] May overlap with JerkassWoobie due to his numerous failed experiments on the sapient Darkseekers and his temperament towards Anna and Ethan.

* HilariousInHindsight: [[https://www.youtube.com/watch?v=1tGXEATdxIc A billboard]] found in the background of a scene promised that a ''ComicBook/{{Batman}}'' and ''ComicBook/{{Superman}}'' crossover movie was in production JustBeforeTheEnd. 6 years after the release of the movie, [[Film/BatmanVSupermanDawnOfJustice it was officially announced]]. Even more amusing is that [[Film/SuicideSquad2016 Will Smith was signed on to appear in another movie set in the same shared universe as that film]].
** There's a scene where the gas prices are over $6 a gallon. In RealLife 2022, the gas prices were ''higher'' than that.

* FanPreferredCutContent: The alternate ending, where Neville realizes that the monsters are sentient and view him as a monster, is much more popular than the rushed and generic theatrical ending. It is also much closer to the book's ending.

* ItWasHisSled: Neville committing suicide in the final pages, after learning he is now the stuff from scary legends, not the vampires.

* MemeticMutation: GODDAMNIT, [[BeamMeUpScotty FRANK]] and WOLL SMOTH, which spun into an entirely unrelated meme.

* IronWoobie: Despite going through so much psychological trauma and suffering, Robert always gets back on his feet, even if he's fully aware the world will soon smack him back on his knees. He just embraces his predictment instead. Even when he eventually commits a suicide, he does it more out of spite than anything else.

* SpecialEffectsFailure: The zombie/vamps are pretty obvious CG. They tried using extras at first, but since it required constant hyperventilation, they were forced to use CG instead.

** NarmCharm: But the context of it makes it heartbreaking.

* HarsherInHindsight: The outbreak caused by a "cancer cure" for 10,001 people. Flash forward to 2020, where a great many mass casualties caused by the Coronavirus epidemic and people are trying to find a cure for it.

* PeripheryDemographic: This film has gained a rather strong (semi-ironic) following among ''[[Franchise/{{Shrek}} Brogres]]'', who deeply admire the scene where Will Smith regains some of his sanity by reciting the dialogue to the original ''WesternAnimation/Shrek''. [[MemeticMutation All hail the Ogrelord.]]

'''You'd Expect''': Once Neville finally get a grasp of himself and stops drinking, he would simply build a wall around his property, especially since for safety he already had to burn down neighbouring houses. This would lessen the issue of noise, provide another safety precaution and would lessen the pressure on constant repairs, which obviously eat materials each time.\\

** '''Instead''': He keeps boarding the windows again and again each day and for obvious reasons it takes a considerable effort from him to even apply basic sound-proofing, while there are still fists smashing over the boards and walls of his house. What makes it stand out so much as idiocy is the fact he never even considers it, despite having to deal with siege each night for years.

* WhatAnIdiot: Neville is the last human left. He's besieged every night by seemingly endless hordes of vampires that aren't too smart or agile and are easily stopped by boarded windows, but make a lot of noise while trying to get inside, driving him nuts and not letting him sleep properly. Robert has access to all goods and materials imaginable and it's not that they are going to spoil within weeks. He has all time in the world at his disposal ''and'' construction experience.
