Oh, my god, finally somebody who isn't in love with this movie. Your post is pretty much a description of my reactions throughout the movie. I mean, I was trying to see the hour at my watch, because it was so senseless and stupid and boring and I just wanted for it to finish... I loved 616!Extremis, so it was that much worse. And he did actually blow up the suits, didn't he? It wasn't just some nightmare I dreamt when I fell asleep after the millionth scene which was intended to be funny but was just pathetic? I couldn't believe it while watching it and I still can't. Tony Stark, Iron Man, blew up all of his suits. Wtf? No, it wasn't romantic or anything, it was just stupid.
For a short while I was happy they finally adressed his PTSD, but then they made it into yet another funny-not-see-it-is-funny-why-don't-you-see-it thing...
Sorry if it's not really coherent, I watched it not even an hour ago and am so disappointed...
