None of this is to say it was a bad movie. On the contrary, I thought it was an interesting concept. Basically, the male protagonist's (Rob) girlfriend dies in a car accident and he went through a period of being suicidal. Eventually, he and another character (Holly) become attracted to each other and begin a relationship and his dead ex takes exception to it and actually appears in his room at very, shall we say, inconvenient times. Rob and Holly then have to figure out a way to make things work.
The actors are great, owning the quirky humor as well as the serious moments. I really, really love the dark humor in here. Especially the scene with Holly in CPR class. It seriously made me crack up, and I had to struggle to keep quiet since I was out in public. There's also some great scenes between the three leads that I really enjoyed.
If you're into quirky, dark material and don't have a problem with adult content, give this one a try. An interesting note for any Whovians out there: Nina's father is played by David Troughton, son of the second doctor, Patrick Troughton.
