Isn't that what this forum is built on?
Honestly, I only saw Avatar for the first time a couple of weeks ago. It was the kind of chlorine-bleached adventure that always, or generally, becomes hugely popular. I didn't think it was bad, but I didn't find it particularly exceptional either (and visually, I remember being more impressed with the Dark Knight's IMAX scenes), solid three stars. Of course, I could have been just an exceptionally jaded day, I've been unable to watch a lot of movies recently. Still have the Inception blu-ray waiting, I saw it in theatre but I want to see how it scores for repeat watchability (something that I've always been disappointed with Nolan's movies).
