Timecrimes is very scary and engrossing and has a simple, yet very tricky plot. The premise has to do with time travel, with someone who panic stricken, being chased by a crazy man in a pink bandage, runs right into a time machine. I just gave away a kind of surprise, but no one reads this blog anyway, so who cares.
It had the texture or feel of being an anxiety dream, as well as a horror story, as well as science fiction. I got kind of confused towards the end, as the main character kept messing up events in terrible ways and trying to make up for them, but I still enjoyed in immensely.
