Query: Entertaining but a little dark

I really liked this movie and found it very entertaining. However, there is a dark undercurrent to it with Natalie Portman's character's trust issues so it's kind of hard to watch if you are in a bad mood, but I at least think they do a great job of acting in it, and it is a very entertaining movie if you are just looking for something fun to watch.
