This is a film (a film, not a movie) about coincidence and fate (is there a difference?) and about changing your life. It moves slowly but, in this case, that's not a bad thing. It's really quite fascinating.

Some interesting visual effects; some intense scenes (and some tense ones); fascinating bit at the end (as Ice said, if you came in at that point, you wouldn't know what the hell was going on).

Overall, I liked it.

Oh, and I want that house they show at the beginning and the end. Apparently, it's in Cornwall in the UK. Stunningly beautiful location.
