Bad acting done well
If you want to learn, how to act bad, watch this movie.
I don't know if it's the bad writing of dialogs or the actors having no clue about acting or both together, but it's really bad.
I can't point out why it is bad, because some of the actors seem to try really hard, but they just can't. I assume you can't act good with *beep* dialogs, so even if some of them could act, they weren't able to. Just like famous actors couldn't act to Lucas' Star Wars Episode I-III too.
