It's for me hard to remember the TV Series or even the last movie. I want to compare this latest movie with either of those. All I can say is that this movie is good, and it stands alone fairly well. I'm sure there are some in-jokes and inside references that I missed; but honestly, it didn't rely too much on that. This movie was like a 90 minute episode from the first couple of seasons.
The acting and special effects were both done well, and the story was intriguing. The movie kept my attention the whole way through.
If you like the X-Files or horror/scifi, rent this movie, and I think you'll be pleased.
