Inception

I signed up to Amazon Prime inadvertently (they make it very easy to do) but since I've got it I'm going to use it to catch up with movies I quite wanted to see at the time of release but never got round to. Last night was Inception.

Inception is brilliant- and intelligent- but two questions:

1. Can Leonardo di Caprio do anything other than glower?

2. Why must all the dreams be so violent?
