Rats

A bunch of scary glowing rats go out for some food and terrorise a nearby mental institution. Apparently, they're so bloodthirsty because they all want to suck up to their master, a gigantic superrat who makes them perform Satanic rituals and chant Barry Manilow songs. There isn't much to say about this movie, you've seen it all before. It's mostly boredom, but there are in fact two scary moments, namely the bathtub scene where suddenly a giant CGI rat comes out of a CGI nowhere and some other rat licking up blood, which is goddamn creepy. Don't do that, rat. Generally this thing just isn't entertaining. If you want a good killer rat movie, well I can be of no assistance.
