Mini-Review: 'District 9' is brainier, but not grandiose (and that's a good thing), than your average alien movie. Seeing 'District 9', you get the feeling that this is something which is actually plausible - IF there were aliens, and IF they were to be stranded here in large numbers, this is more or less what will happen. This must also be the first "humans vs. aliens" movie, where I actually ended up rooting for the aliens.
