Indiana Jones and the Kingdom of the Crystal Skull is not that bad. With the crap that George Lucas has been putting out recently, I'm surprised the new Indiana Jones movie was not worse. The increased use of special effects and CG definitely hurt the movie but not as much as that Gungan idiot hurt Star Wars. Ultimately, the goal and ending of the movie were pretty poor but the early and middle parts of the movie were plenty decent as far as Indiana Jones' style is concerned.
Funny that aliens and flying saucers are less reasonable than the hand of God but I think that's just the way my mind says the world of Indiana Jones is supposed to be.
