I love the technology. '4D' is much better though (lot of them in Theme Parks etc and there is one at the London Eye)
I can't work out whether 3D is good or not for films. Obviously its good for cinema but only the top-end studio productions can utilise it. Low-budget Independant movies won't/can't use it so they may suffer in the future.
Not that I'm against new technology or anything.
Avatar looks like it has the potential to be amazing and a big step forward in 3D films, am looking forward to this one hitting the flicks.
Apparently its going to come in as the fourth most expensive film ever
