“Swim” (*** out of four) was a stylishly done B-movie about a family (Jennifer Field, Andy Lauer, and others) that gets trapped in their flooded vacation rental and have to escape from a ravenous shark that has made its way into their house but have nowhere to go since the entire city is flooded and is a giant river. Opening scenes are a little plain and heavy-handed but once it gets going- film delivers the goods with scary shark scenes and efficient direction and filmmaking. Bonus: the shark looks especially vivid and terrifying!
