This isn't a bad little movie. It's got some quite good moments, the acting is totally acceptable and the actress playing the landlady was good. The idea was great and the location well choosen. But for me it lacked suspense, there were no surprises, it was mostly all given away in the trailer. There was a twist at the end, but I'd think most people would have seen it coming.
It's not a "gay movie", it's just a movie where the leading character happens to be gay. As another reviewer said, it would have worked just as well if the lead were straight. Personally I'm glad they make films like this that aren't about gay issues or themes, but just have lead characters that happen to be gay without being flamboyant.
The DVD extras amused me. I won't say I was disappointed, because I wasn't really expecting much. They had an "interview with the cast", which involved interviews only with a couple of the supporting actors and not any of the leads. Personally I couldn't get very interested in someone discussing their role as a guest at a party with a couple of lines to say. If you're going to interview the cast, you should at least feature your principal actors or not bother.
So not great, but not bad either. Nice try, but could go better on building up the suspense.
