First of all please tell me how the hell a bunch of plant humanoids (never read the comics, and if I'm wrong it's mainly because it ain't explained really well in the movie.) can destroy and rip the limbs off of about 15 IRON MAN SUITS. THOSE THINGS ARE MADE OF EXTREME ALLOYS AND SHIT.
Why the hell would Pepper get so mad at Stark for building cool-ass suits that for sure will be useful sometime in the future? WHY???
I did like the Mandarin guy. That was funny

Oh wait, I just remembered; in the previous movie didn't Stark go through a lot of shit to find the supreme element/particle/molecule/thing that powered up his suit like a hundred times and assured his safety from being killed by the shrapnel?
Also, if he could have taken off that crap that threatened to kill him every single day all along, why didn't he do it in the previous movie where he was literally dying and lurching until he found the awesome legacy from his father?
Yeah, sure, he blew up all of his long life work that probably cost him all of his savings to please Pepper and make her forgive him (FOR NO DAMM REASON) at the end; but now he is basically homeless. His house blew up, his machinery was blown up, he blew up his suits... even the giant bunny rabbit blowed up!
Also one thing that made me really nervous: The original Golden-Scarlet suit doesn't appear ONCE.
And last but not least: At the end of the movie Stark said "But one thing is clear, I am still Iron Man." NO YOU'RE FUCKING NOT! YOU BLEW UP ALL OF YOUR SHIT AND EVEN TOOK OUT THAT AWESOME GLOWING THINGY IN YOUR CHEST! Yeah sure, Tony's still alive and kicking, so he can make a suit anytime he wants; but it's as if the original just died. That's what I hate the most.
