It's interesting, though perhaps unsurprising, that the films at the bottom of everyone's lists are so similar.
I mean, you've seen The Incredible Hulk, so you should know that "perhaps unsurprising" is quite the understatement.
Yeah but even the others on the bottom, generally, being 'Iron Man 2,' 'Iron Man 3,' and 'Thor: The Dark World' is pretty striking to me (yes, that can be a Thor pun if you want to consider it one).
Iron Man 3 isn't too bad actually, it just is very low-stakes and "boring" in terms of "superhero versus bad guys" action. It isn't the movie fans wanted.
I'd honestly go so far as to say that IM3 is the most underrated MCU film. I really liked how it was a Tony movie first & an Iron Man movie 2nd, & how it dealt with his PTSD in the aftermath of The Avengers.
The most common complaint I see about it is the Mandarin twist, but I personally loved it: I thought Kingsley was hilarious; it enabled him to be scary in the first part & a sort-of comic relief toward the end, & it left the real Mandarin open for future films (e.g. Shang-Chi).
Plus, there's just something so chilling about seeing 40 of his suits fly in & wreck house. It really makes you appreciate how this guy with no superpowers can dominate any fight with just preparation & his wits.
