Watching this movie, you just have to ask: What were they thinking? There are so many noticeably bad parts of this movie, you might get the feel that its intentionally poor, as some sort of joke.
I think the worst part about the film is the directing. There are so many bad uses of camera angles and other cinematic elements in this movie that are laughably bad. The funniest example of this would be in the beginning where the party guests are receiving their invitations by email - The same camera angle is used for each shot (which last an awkward 2 seconds a piece) and the same computer screen with the same desktop/window/program etc appear. It even looks like the thing is shot on the same set each time. The whole sequence was also completely silent, with no music, or sound effects. Overall, it was a poor way to convey the idea that an email was being sent all over town.
If you listen closely, you may notice that the music sounds very similar to other movie sound tracks. This is no surprise- most songs, including the one that opens the movie, are in fact slight alterations of scores from other movies (See if you can guess which ones). Also, I noticed that the music is not played by a real orchestra. It sounds like its been written and played through a low end midi keyboard. If you are familiar with the LucasArts SCUM adventure games, the timbre of each instrument sounds like something from the IMUSE engine.
Everything else about the movie just plain sucks. The acting is terrible. The script is derivative (Ferris Beuller?). There is no joke in the movie remotely funny, unless you see the whole film as one big joke, being played on a paying audience. Don't rent this. Don't even watch it when it's rerun on comedy central. Just forget this - it's terrible.
