The Last Airbender : Worth a watch?

I mean, I see all the 1 star reviews so there's no chance of it being good. But even worth watching for a laugh, or would I just waste 2 hours of my life?

I've watched both Avatar TLA and Legend of Korra three times each so far, so my love of these series SHOULD insulate me from this film's obvious terribleness. But I don't ever want to think less of the Avatar world.

Worth it to laugh at, or complete waste of time?

If you look at it as its own thing its fairly decent, there are points where it becomes so bad it's good and other points where I found it touching and emotional. However if you compare it to the show you will most likely hate it. Visually though I thought it looked amazing and the score was beautiful.

I would say no. It's probably the worst big budget commercial film ever made.
