History YMMV / TransformersRevengeOfTheFallen

** Alice, a Cybertronian Pretender who could perfectly mimic any human. She could easily have become a threat had she [[KillAndReplace assassinated and imitated someone like a military general]], where she could have [[MoleInCharge actively worked to worsen human/Autobot relationships and sabotaged NEST]] from the inside. But instead, Alice's only involvement is with the RomanticPlotTumour.
** Devastator. They give us a giant behemoth far more monstrous than any previous Decepticon combiner and what do they do with him? Drive a railgun through his head after fighting only two Autobots and accomplishing nothing of relevance aside from freeing up the sun harvester, which practically ''any'' of the Decepticons could have done by accident. Even worse, despite Constructicons being mass-produced in this universe -- and therefore carrying the implication that ''multiple'' Devastators can be formed -- this is the only Devastator that appears over the course of the film series.
** Even fans who don't like this incarnation of Jetfire still think that killing him off was a bad idea and that he'd have more potential alive than dead. In fact, part of the reason some fans don't like this version of him is BECAUSE of how much potential they feel like his death wasted, not to mention the fact that some see it as an unnecessary darkening of the Jet Prime mode from ''Armada'', where Jetfire didn't have to die to combine with Optimus and could return to being an individual robot afterwards.

* MemeticMutation: Optimus' line "Give me your face!" right before [[spoiler: tearing the Fallen's face off.]]

** Scorponok just happening to show up during the battle in Egypt where he mauls Jetfire before he's unceremoniously disposed of, having apparently managed to avoid detection for two years after his defeat in Qatar.

** Some fans think Jetfire is a pretty faithful update of the classic G1 character, an excellent performance from Mark Ryan, and an entertaining, funny character, while others think he's not faithful enough, ugly, a hackneyed walking "old man" joke, and that him dying was a big waste of potential and an insult to the ''Armada'' version of the character.

** Jetfire for being a pretty faithful update of the classic G1 character, an excellent performance from Mark Ryan, and for being an entertaining, funny character.

** And, apparently, they weren't intended to be parodies of urban African-Americans at all, but instead jab at the subculture of white males who emulate hip-hop mannerism to an offensive degree. Not a ''horrible'' idea in-and-of-itself, since the Autobots were already shown to adopt Earth cultures they most identify with and this could've been presented as a rather entertainingly cynical look at their cultural appropriation. However, the commentary falls somewhat short since they're, y'know, ''robots'' that have no ethnicity, leaving the audience to draw the most logical conclusions over what they're supposed to be representing, especially since their faces look like racist caricatures anyway.

** Soundwave ripping a satelite and using his tentacles to inject with with white stuff.

* SophomoreSlump: It's near-universally considered to be worse than the first film and ''Dark of the Moon''.

** Devastator's [[VulgarHumor wrecking balls testes]]. Appears for about ten seconds as a throwaway gag. Tends to get mentioned often when bringing up Devastator's movie incarnation.
