Intense, exhilarating, brilliant. Bought this for my daughter who drums, she loved it :)
Hard to review. It's a good film, a very good film but I don't think it's an all-time classic.
A lot shorter than I remember and for some reason the story felt less involved, especially the whole Natalie sub-plot. I remembered a lot from previous viewings, not sure if that helped. I've also seen the forward version before.
If you've never seen it before make sure you keep your eyes open throughout as there are several subtle clues. The story runs backwards and it will keep you thinking long after viewing as you piece it all together.
