Personally, I'd consider Underworld: Awakening's 3D sub-par; the cinematography really didn't take advantage of 3D and there was very little in the way of pop out of the screen. Also, the film's 2.39:1 aspect ratio and resulting letterbox presentation further compromises the 3D effect on 16x9 TVs.
I'd say that Journey to the Center of the Earth, Journey 2: Mysterious Island and Hugo are the current benchmarks for live-action natively shot 3D movies, surpassing even more well-regarded titles like Avatar in my opinion. Its also no coincidence that all three of those films are presented at a 1.85:1 aspect ratio, using nearly all of the screen on a 16x9 TV, which makes the 3D imagery even more immersive.
Also, if you want to see some good live action 3D, try checking out some of the Imax 3D BluRays like Hubble 3D, Space Station 3D, Grand Canyon 3D Tahiti: Ultimate Wave 3D and Under the Sea 3D; Imax features can be a little dry in terms of presentation but the 3D photography is uniformly stunning.
