I think you've just slated the fabulous cinematography of Jack Green, one of the greats and an Eastwood Favourite.
Serenity looks like Lawrence of Arabia in comparison to Star Trek, although familiarity with 'Firefly' is required to get the most out of it.
I'm delighted he's doing The Avengers. If he can bring half the charm of the firefly ensemble to it then it should be a thing to see. It really depends on how much writing he's done on it. It's someone else's screenplay I think
