Part of me wanted to like this movie because I had a lot of hope for Jack Black and Ramis. I was way wrong; I gave two stars for the good acting - it might have been a cheap movie, but the actors did a good job (and I was surprised to see so many familiar faces!).
The story...was utterly childish. It was like someone found an online list of questions about the Bible and made a movie of it - a list that had been answered and put to rest ages ago (no pun intended) - but instead of seeking the answers someone just wanted to perpetuate the questions. I don't hold anything against the actors - they're actors, they were being paid to do a job, simply put.
The movie itself seemed to be of decent quality; what homework was done on the historical part of things wasn't to horrible. One part that did bother me though were the virgin sacrifices in the fire of the statue of Molech (the bull in Sodom); in the movie, drums start playing loudly and people start cheering loudly as well, which was great (because that was historical, which was a nice surprise for a movie like this), but the virgins were grown women who seemed to be okay with being the sacrifice. The reason this bothers me is because in reality it was children who were sacrificed (felt like this movie was making light of such a horrible practice); a fire would be made in the belly of the statue and the hands of the statue would heat up (the one in the movie doesn't have hands), the children would then be placed on the hands and basically get cooked alive - drums would play loudly to drown out the screams so the parents wouldn't have to hear their kids' cries. Really horrible stuff. There are lots of misrepresentations in this movie, though.
The "comedy" in this movie is sophomoric at best - mostly elementary, really. Early on, Jack Black is cooking (a rabbit?) on a stick, and holds it up while asking what it looked like... I actually laughed at that - not because I thought it was funny, but because I was sitting there wondering how a grown man could still think something that childish is funny. It was, like I said, elementary.
I think the humor is more cringe-inducing than funny (the entire reason I watched this movie was because it somehow got 4 stars) - there's no way this movie is 4-stars-good. The guys talk about a girl one of them is in love with, while watching her stroke a couple of spears (yeah...); Jack Black tastes human feces to help him better track some people down (somehow), which then turns out to be bear feces I guess; Oliver Platt has an odd fetish as a pagan Sodomite priest who likes to be rubbed down with oil by Michael Cera...you can tell it was intended to be funny, but like I said, most of the comedy in this movie is more cringe-inducing than funny.
Overall I gave the movie two stars, because the actors did a good job at acting. They were just the victimss of really bad writing and story-telling.
