I'm in the camp that goes to movies for basic entertainment and F4 definitely did that for me. The Hulk was so slow and boring that I actually fell asleep during it. Worthless story, worthless film.
F4 was more of an intro movie the way that X-Men and Spiderman (1st movies) were intros. Hi, these are the players, and this is how they got their powers, and this is their situation. Nothing to crazy going on there and the F4 have never had the inner turmoils to deal with the way that X-Men or Spidey has. Spiderman for sure as he has had a lot of 'heart' in all the comics and they have maintained that on film.
F4? They are superheroes, they fight bad guys, they are a team, they have some internal drama.
Oooohhh - Fire, rock, hot chick... Good effects, some explosions...
This is about as average as a film can be. Far better than the poor reviews. To call it LESS than average is wrong. Because Spiderman and X-Men are not 'average' - They are far superior films. If your expectation is A+ work, and you see C level work, you will be disappointed. If you expect C level work, and you see C level work, you will come away happy.
Yeah, I'm easy to please.
