Avatar was the gold standard and nothing has surpassed it since , although I was also impressed by Life of Pi.
3rd rate post processed catch-penny type films make up the bulk of whats out there - the most abhorrent i have ever seen was Tim Burtons "Alice in Wonderland" how that left the cutting room floor is a mystery to me.
Joe six-pack see's the 3rd rate movies and assumes that this is as good as it gets.
3D Blu Ray is the only way to watch theses movies too - knock-off "Rips" from TPB are fine for 2D movies
but somehow a lot is lost in any subsequent transcodings. I've not found any sources for high quality 3D streams (reccommend one to me?)
To sum up .
1) Very few examples of 3D movies actually filmed in 3D and produced by someone who has taken the time to make best use of the medium.
2) Too many examples of poor content with lame storylines filmed in 2D and post processed to 3D. These films are better seen in 2D (if at all)
3) TV Manufacturers, like the bad 3D movies tried to jump on the bandwagon and hence there are a lot of shitty 3D TV's out there.
It still costs too much money to create and enjoy 3D movies the way they were intended.
