Shaun of the Dead
The plot: Zombie's begin to take over the streets and it's down to Shaun to lead his friends to safety. Set in a romantic back-drop, Shaun of the Dead is the original Rom-Zom-Com.The good: It's funny, it really is. It has some great moments. That's it, it's just very funny.
The bad: Although it calls itself a "rom-zom-com" it's obviously all about the comedy with very little horror or romance. The humour might be a little British-y.
Conclusion: As I've already said, it's funny. Worth a watch.
