avatar/hd/ trailer is extremely impressive from at least a technical perspective. The CGI is very nice. And if reports are to believed, very little is in it's final completed form. The plot is pretty basic, and can be summed up as Dances with Wolves with Aliens. As long as there's no gaping plot holes or horrific acting and dialogue I'm fine with the deliberately not terribly original plot. Not all stories have to be completely new and original. If Hollywood would do more classic story ideas in different environment movies instead of 'reimaginings' and remakes I'd be a lot happier.
