I feel bad for the writers yeah they get paid but reputation means more right?.
IM3 was not attention grabbing. The way the suit comes on reminded me of Guyver and it was interesting for a little while. They showed of the new trick too often. Peppers' twist in the end was neither shocking or unexpected.
The plot was unnecessarily elaborate; the plot twist, regarding the Mandarin, although clever, contribution little to the film and made the rest of Ben Kingsley appearances pointless. They seem to have borrowed that trick from the people that made The Other Guys and messed it up.
I liked stark depressed and wanted to see more reclusive behaviour. The bad guys seemed too bad - they were not convincing. Their objectives were lame. Why anybody would go after Iron Man in a Helicopter so willingly astounds me. The "bad guys" should have been pleased they were healthy again. Pepper had the same treatment and didn't turn into a thoughtless meat head.
The grenade style exploding bad guys seemed "silly", exploding magma seems more suited for them.
Somebody did try but IM3 is weak.
