Second, lemmie say that the comments for this article will contain spoilers! This is a GREAT movie. If you haven't seen it, don't ruin it for yourself.
Since I actually got a request for how I should handle the review, I'll follow it here.
1.) Were the actors believable?
The acting was superior. Mel Gibson and Joaquin Pheonix were superb. Not only that, but the character development was monumental! Acting was not a low point in this movie.
A reason for this, if you look at the imdb page for the movie, is that there are only like 10 actors/resses in the movie that have a speaking role. Most everyone else is just an extra. This allows for character development on all the characters in the movie, and the direction is only concerned with few actors. That way you get quality instead of quantity.
2.) How significant were the morals and the belief systems, in the movie?
Believe it or not, there is an underlying spirital/moral story in the movie. It has Christian overtones and struggling with faith. As I said, it was a part of the underlying story, so it was quite significant. In fact, the name of the movie isn't just about crop formations, it also multiple meanings in the movie, and one of the major ones is about Christian faith.
3.) What other films were directed by the director and produced by the producer?
Well, since M.Night Shyamalan wrote, directed, AND produced the story, I guess we are only talking about one person here. He's most known for The Sixth Sense and Unbreakable, but he has a few more you can see on his IMDB page (like he wrote Stewart Little).
4.) Would you recommend that I see this? If so, where? In the theatres, on dvd/video tape, or on cable, or else where?
I am recommending this movie to everyone in theaters. It is a suspenseful movie, that scared my wife quite a bit, but I'd be surprised if this isn't nominated for Best Picture. It was a SUPERB movie.
5.) Was there any sex or sex-like content in the movie?
None. I think at one time one of the actors tells a story about kissing a girl in high school.
6.) Was there any violence that could have been avoided?
Not really. There isn't a lot of violence in the movie (some, but not much). Its mostly fear and noises that make the movie scary, not gore.
7.) Were there any swear words?
Yes, but not a lot, and most of them were nothing more than comedy relief (I don't want to give any part of the story away, so just trust me on this). But the swear words are VERY minimal.
All in all, I thought this movie is one of the best I've seen. I'd see it again, if I could get my inlaws to watch my son again. I wouldn't go into the movie thinking that its another Sixth Sense, because it isn't. All his movies are different types of movies. I don't think anyone will be disappointed by the movie, unless they scare easily. There are a few "jumpy" points that made my wife rip my arm outta socket.
