The movie is about how everyday life is not exciting, it's not interesting, it just happens. Yes but that has to somehow be communicated to the viewer in a way that is, at the very least, interesting to watch. There has to be something to make you care about the characters you're spending 70 minutes with before spending a further 5 watching them get slaughtered. As cliché piled upon cliché, it really began to bug me as I wasn't watching real people, I was watching cardboard stereotypes that I simply didn't care about. And when said stereotypes are being portrayed by actors who ranged from painfully self aware and amateur to downright hopeless, I could never get past the fact that I was watching a film and I could not wait for it to be over.
High school shootings in general and Columbine in particular could use a truly brilliant drama being created out of them. This wasn't it.
Nothing precious, plain to see, don't make a fuss over me. Not loud, not soft, but somewhere inbetween. Say sorry, just let it be the word you mean.
