I bought this DVD purely because of the bargain price, to be honest not expecting much but feeling that if it was even half decent then it was worth the purchase. My expectations were well exceeded. It's not quite the Matrix, but in it's favour it's actually faster paced. The story is good (I've never read the comics on which it's apparently based so I came with no preconceptions), the effects are great, and the ending, whilst probably not qualifying as a twist, I very much doubt that anyone will be expecting. A thoroughly enjoyable 2 hours and very definitely re-watchable.
