I watched a film called Crawl this week. It is set somewhere in Australia but it could be anywhere, the location isn't that relevant to the story. An unpleasant bar owner hires a Croatian killer to kill an old man who runs a garage and auto shop. It isn't very clearly established why killing him was necessary but the important thing is that the Croatian plays a big role in this film. He is played by an older actor and does a good job of portraying someone to whom killing is a business rather than a personal thing.
The film is slow paced and I would say was a thriller rather than a horror film. There is nothing supernatural in this story. The tension is kept wound up tightly, there is surprisingly little music in the film, what there is seems quite sparse. I don't know if this is a deliberate thing or not. Not sure it works entirely, having watched The Entity recently I know that sound/music can play a massive part.
At the end things get a bit bloody but its not a gore-fest.
Overall, this wasn't a bad film, I'd have to be in the right mood to want to watch it again though. There are some things that happen and you think the story will come back to but it doesn't. So, it is slightly frustrating that some of the characters aren't developed as much as you want.
