unsatisfying movie

Rating: 6/10 (6 July 2016)

The story: Michelle got into a car accident. when she wakes up, she is locked in a room in a bunker. The man, Howard, who put her there tells her Earth is under attack and she should just stay in the bunker with him for safety. Of course she doesn't believe him and tried to get out of the bunker.
There are several problems with this story line. (1) Why does Howard lock and chain her up after rescuing her? Makes no sense. (2) If the Earth is really under attack, there would be evidence from within the bunker. E.g. emergency radio broadcast, the disappearances of normal radio stations, or frantic CB radio messages. A well prepared survivor like Howard should have those items. Why would he not show the evidence to Michelle, knowing she is skeptical? And why is Howard not aware that Michelle would be skeptical, after he locked her up?
When Michelle finally escape out of the bunker, she is greeted by aliens attacking the Earth. That's a surprise, because up to that time the movie tried to make us believe Howard is lying. Unfortunately, this surprise is kind of forced. It is not logical, but made that way just for the pure purpose of surprising the audience. And after the surprise wears off, the movie come to an end abruptly.
There is also a lot of fluff in the movie. Whenever people are telling each other their life stories, I fast forward.
In short, this movie builds up suspense and then gives an off the wall twist to surprise you. But with no good story line to support the twist.
