To appreciate this film you need to like seemingly random humor, parody and satire, and weird ideas brought to life on film... you will probably like this movie.
The film is a strange satire/parody of "The Blair Witch Project." Even if you haven't seen the film it's satirizing, as long as you know some basics about the film, you'll get most of the jokes. I've seen 5 of the 6 thumb films. (excepting "Frankenthumb") I consider this to be the best of the six. This has some of the most absolutely ridiculous and funny moments I've seen in a parody, especially recent parodies. And the amazing thing is that the film actually manages to stay pretty clean. There's not a whole lot of swearing, there are some sexual jokes, but they're not overwhelming or blatant, and it's something you can watch with children without worrying about the content.
The ending was a little too random, referencing another thumb film, and the DVD menu is a bit of a pain in the ass... switching you to random menus... (on a play of the 'lost in the woods' idea) which brought the movie from a 10 to a 9.
However, the film is very enjoyable and has some of the most ridiculously funny moments I've seen in a parody (once you get to a screen that will play it).
I recommend it for anyone who likes random, weird, satirical humor.
9/10 - weird, satirical, random fun.
