3D is a useful technique when done well and used for the right reasons, just as any cinematic convention such as the BCU or contra-zoom. If used the right way these techniques add to the experience - if not they can stick out like a sore thumb.

3D is also the industry's new toy and there is a danger that many films that do not want or need the 3D treatment will get a stereoscopic makeover just to be up with the "in-crowd" of films. Personally I find many 3D films to be very headache-inducing, but if they are done well (Prometheus, Avatar, Toy Story 3) then I can risk the pain for the augmented experience.

3D isn't quite there yet - but it's certainly on it's way and more directors and cinematographers are learning how to work within it's confines and toolsets... all we need to do is educate the Producers and Film Execs so that they know when to use 3D and when to just leave well alone (Avengers - yes, I'm talking to you)
