I loathe 4DX, and nothing will change my mind about that. It's supposed to be a film, not a theme park ride. 4DX adds nothing to the cinematic experience in my not remotely humble opinion. Quite the opposite, in fact.

As for Avatar, it would be dangerous for me to watch that in 4DX, as it would piss me off even more. Read my thoughts on the recent film here, if you're brave enough...
