I’ve now seen the first two of the big summer blockbusters — Iron Man and Indiana Jones and the Kingdom of the Crystal Skull.
They are both worth watching, but Indiana Jones was clearly better, in my opinion. I thought the new Indy movie held up very well to the prior versions, though they will never make a better one than Raiders of the Lost Ark. Iron Man, while good, pales considerably in comparison to recent comic-book-type movies, such as Batman Begins and Spiderman (it’s better than the crappy recent Superman movie, though). I’m not a big fan of comic books, I must admit, so I knew nothing about Iron Man going into the movie. It was good, but not great.
Indiana Jones, on the other hand, was nonstop action and was full of all the little things that made the first three Indy movies so fun.
Try to see them both, but if you have to pick one, go with Indiana Jones. You won’t regret it.
