I went with some friends just because there was a group of us going. I had moderate expectations, but was really surprised at how much I liked this movie. The characters were true to the TV series, there was a lot of humor and the plot was well thought out.
I was very surprised (and pleased) at the lack of sexual references. The only problem I had with the movie was the use of foul language. It wasn't terrible, but it could have been less.
Overall I highly recommend this movie to anyone, especially fans of the original TV series.
