it's just light hearted action with some good style and a somewhat fresh / unique take on the whole cape and tights thing. it's bloody and light hearted, feels something like a teenage Tarantino flick (without all the self-concious stylization and referencing).

if you enjoy action pictures or superhero pictures at all, I'd highly recommend trying to catch it on DVD.

and as far as my point about the marketing, it's not as if it was AMAZING, but I thought it was marketed just as well as any other big picture, so it would be baseless to say that was the reason it didn't do great at the box office.
