Like Lost, and Stephen King's The Dark Tower, the Deaths of Ian Stone does a great job of building up a mysterious story and loads of questions, but sadly doesn't really follow through at the end.
Ian Stone is a ice hockey player that gets hunted down and killed by a strange monster. The next day, he's an office worker who's girlfriend turns into a monster and kills him. The day after that, he's a taxi driver who gets stalked by monsters. The only constant is a blonde girl who turns up in every incarnation. Who is killing him every day and why? And who is the blonde girl?
This was all good stuff up to a point, but when things start being explained, it all becomes a bit ho-hum. Not a bad film, mind, the creatures are pretty good creations, and there's plenty of tension, but I think the film makers were looking towards creating a Clive Barker-like worlds-within-worlds mythology. It didn't quite work. For some reason the baddies all dress like Matrix people. Didn't quite get that bit either.
It's okay, just don't get yourself too excited when watching the first half.
