I don't know, I guess I sorta expect the explosions and I think they should be there. I mean, Tony Stark is a weapons manufacturer. He makes explosions. He has a big huge gigantic ego. He likes for things to explode. He makes that happen.
I mean, fight scenes in a superhero movie doesn't not make sense. It just how it is. Superheros fight often. And when they are wearing super powered suits armed with various exploding things, stuff is gonna get blown up and smashed.
And then somethings were there to drawn a point. Like the scene where Tony is drunk, in the suit, on his birthday, and a bunch of party-goers and tossing things in the air for him to shoot. I really honestly feel like this was the first time they really drove home the point that he is an alcoholic, and can be/is an obvious danger to people, since suit and alcohol don't mix well. I was actually telling my boyfriend how I didn't feel like the first film touched on his alcoholism enough, but I feel like this film definitely has, and I'm glad.
And yeah, people misbehaving in theaters is so aggravating! The girl next to me, texted the whole time. And left the volume on her phone on. Not even kidding. And she kept updating her boyfriend next to her where her friends were. Then she kept asking about what was going on on the screen. I bet if you wouldn't have texted while the movie was on, you'd know.
