There's good, there's bad... it was enjoyable enough. It was tough to get invested in the plot or characters, but the acting was decent, and the story was compelling. It's very plot-driven, reminding me more of a 70's movie than a modern action/suspense movie.
The Commuter tells the story of an insurance salesman who is decent at his job, but it's a bit monotonous. Eventually, you discover he is an ex-cop, and in his commute home get embroiled in a plot to find a passenger carrying a bag with unknown "dangerous" contents. He must find this passenger... or else!
The opening of the movie was a cool concept, showing how monotonous the lead character's day/life is. Taking the same train, going the same place with the same people. It was pretty clever. But then, he gets told of a crazy job, if he can just find a person! He's an ex-cop, so he's got the right skills for the job! But we really aren't invested in the character, and the situation is a little too convoluted to really be engaging. Soon, people are dying and the situation goes from bad to worse. The action is decent, even if the plot is a little hard to swallow.
If the concept intrigues you, the movie is enjoyable enough. There are some cool scenes, but nothing great or terrible. It's worth the time if you have MoviePass, but probably not worth the money if you don't.
