But Alice in Wonderland wasn't true 3D, it was done in post. Last 3D movie I saw was Dredd and that was ok. People rubbish Avatar a lot here, but I thought the visuals were great.
The problem with 3D is that it's inconsistant. You'll get one out of every 5 titles that is decent, especially with non animated stuff. 3D can be really well done if they apply themselves whether it be shot in 3D or post 3D. Avengers was post 3D and looked great, and so did Titanic. Spider-Man was shot in 3D and doesn't look too good. The culprit here is the studios that are trying to push this technology but don't actually put time in it. The equipment also varies too much from one to the other. There is also a big difference from 3D at the theater and at home. I absolutely hate it in the theater but love it at home. But again, there is a vast inconsistancy from equipment to equipment. My setup absolutely blows away any experience I've had in a theater, but my friend's setup is really poor quality, dim, and headache inducing. I haven't had one person come watch Tron: Legacy, Prometheus, Avatar, or Titanic that hasn't left my house stunned. 3D is a novelty though and it's not for everyone.
