The best-reviewed science fiction film to come out in theaters last week was not Cowboys and Aliens but Attack the Block — a film that it’s entirely possible that you didn’t know existed until right this very second, because it’s been shown on a total of eight screens in the US so far. Why is that, and is it fair? I tackle this question in this week’s FilmCritic.com column. Go over and find out the reasons this flick is little-seen — and if it has any chance of being better seen.
