Iron Man 3
Wow did i ever hate this. The story is rushed and the dialouge is forced. The entire movie doesn't even feel like an Iron Man movie. Tony is barely ever even in the suit. I was okay with them making Tony seem weak and having his problems but the whole anxiety attack thing didnt go anywhere and they didnt just make Tony look weak, they made Iron Man look weak. The suits kept breaking all the time making Iron Man just look disposable. The addiciton metaphor fell flat too. I liked that they gave dialouge and personality to the henchman though, that was a nice touch as was some of the jokes but others fell flat and were ill timed. Speaking of personality Don Cheadle had absolutely none and Robert Downey Jr really didn't seem to be into this movie.
Here was my biggest problem though:
SPOILERS:
They turned Mandarin into a complete joke. Mandarin is Iron Man's biggest Villain and the previews and the setup in the movie makes him seem like an impressive, badass villain and then he turns out to be just another dumb joke. I wouldnt have been as mad at Mandarin turning out to be a front for Killian if they hadnt made Mandarin so damn stupid. Once that happened i didnt give a damn about the rest of the movie. Also the scene at the end was stupid and just another dumb joke. That's all this movie was, a joke. Also i really hated how in a quick scene, they had him getting the shrapnel removed. It made the plot of the second movie pointless.
