This movie is a bad adaptation of a good book
SFW is not a bad movie, in my opinion. I like it, and I even read the book because I like it. However, upon reading the book (a few years ago), I lost some respect for the movie. It totally missed the point of the book. Either that, or the filmakers changed it deliberately.
The book isn't a sendup of fame and pop culture, like the movie is. Sure, it does have some aspects of that to it, but the book has a lot more to offer than that. I see SFW (the book) as sort of a modernized Cather in the Rye. It's a story about a person who has trouble seeing the value of the society he's part of, and how he deals with that. In the book, Spab isn't an angry, rebellious burnout, like in the movie; he's a deeply troubled person who is having a hard time finding his place in the world.
In addition to changing Spab's character, the movie also changes Wendy, Stacy (or Janet, as she's known in the movie), and a few other characters. That's in addition to omitting a few chracters as well, like Frank Dice, who's very important in the book. Aside from the characters, the movie also moves events around, omits important plot points, and even drastically changes the ending.
If you've seen this movie, I recommend you read the book, it's a lot better than the movie. I like it a lot, and I might even consider it one of my favorite books. I'd actually like to see a good adaptation of the book made, but I know that's probably not going to happen.
