To start, I'm a 52 yr-old father that took his teenage daughter. I thought the movie was okay - she really liked it - but (like many other reviewers) I thought it was unnecessarily long. I mean, they had already decided to split it into two parts, so WHY put everybody through an extra 45 (or so) minutes of watching them sit in a tent, sit in the woods, or sit on rocks? And what about meaningful dialogue? I haven't read the books, but HOPE that they have SOME. And WHY can they 'teleport' out of some situations, but not others (re: snatchers)? My daughter has seen ALL the movies and was asking me. Plus, they need to remember that once they put the audience into a scene, WE, the audience, can't remove ourselves from it. Harry and Ron dive into a frozen pond/lake and 2 minutes later, they're sitting there beside the lake, looking at the sword, barefoot, wearing wet clothes (no coats) and not even shivering, much less worried about hypothermia. Come on!! Either do it, or don't! Unfortunately, you put "Harry Potter" on anything and it will sell out. They no longer have to even consider quality. Just keep cranking them out and watch the money flow in! This reviewer's opinion is just WAIT until the series is OVER, and then buy the boxed DVD set so you can watch it at home an skip through the parts you can't avoid at the theater...
The movie was definitely full of action and LOTS of new weapons! Lots of stuff was blown up and there were some really big explosions - all in hi-def. The blood toxicity issue - which was killing him - came out of nowhere and we had to find out much later what it actually was and meant.
Good parts are the new suit power source and the happy ending (of course) with Stark and Potts finally hooking up. Bad parts were his continuing ability to single-handedly construct massive, complex structures and machines in his basement ALL BY HIMSELF; and Don Cheadle (Rhodes) now flying an Iron Man suit. Probably the most disappointing thing to me was that when Stark thought he was dying, he just goes and gets drunk and acts like a fool - which demonstrates a complete lack of any kind of integrity or character - both of which both IM movies intermittently tried to convince us he had developed.
But, the movie, although predictable in many places, was very good, with great visuals and sound effects. I don't think that many people will be disappointed they came.
