La quinta onda

The reason to watch this is for Cassie's performance. The reason not to watch it is the rest of the movie. It starts promising. An alien ship orbiting and people wondering what is all that about. A massive EMP wipes out all electrical connections (Wave 1). A flood (Wave 2). Bird Flu (Wave 3). The aliens are depopulating the planet. The few survivors who were immune to the bird flu gather and the military shows up to take them to a military base. Through luck, Cassie misses getting on the bus. By then it becomes very predictable. Cassie still intends to reunite with her brother, who was on the bus, and that is the rest of the story.
