I enjoyed the movie. Like young Guyver said, its an odd form of pacing. The first 30 minutes is fast paced and action oriented. Then the middle of the movie for nearly a hour and a half is slow. This movie has more flashbacks than one piece it seems. But the last half hour to an hour is were its all at!
The different take on kryptonion genetics is definitely a... Unique look at things.
I'm not too worried at the lack of humor in a movie. It seems like too many movies are all about having more and more humor in it i actually found it refreshing to watch something that's completely serious. One that's not a horror film.
And honestly it had really subtle subtle subtle type of humor.
However, i never noticed a science vs faith thing. they never really harped on either enough to make me think that.
