I totally agree with all the comments saying 3D needs to make an impact, whether that be negative or positive parallax (ideally both). Just can't see the point with these subtle 3D effect films, you're far better off watching in 2D if the PQ is top of your priority list. It's certainly top of mine with films like The Hobbit and Prometheus, wouldn't dream of watching either in 3D!!
For me, the stand out 3D animated film so far is Monsters v Aliens (although I have to say Brave looks fairly promising). It has outstanding depth for pretty much the entire movie, including close up shots, and more negative parallax than you can shake a very long pointy stick at !! Any fan of animated 3D needs shooting if this is missing from their collection.
As for non-animated (although full of CGI) I reckon Avengers Assemble is superb. The final 45mins or so alone has more outstanding 3D than pretty much any other movie has in it's 2hr plus runtime.
