I have a DEEP hatred of 3D. I don't mind it when you are going to a movie like "My Bloody Valentine" every so often for that little extra hilarity, generally though my reasons are:
1. I wear glasses... nothing like watching a film in discomfort
2. The glasses are usually the cheapest plastic lens you can get and produce a verticle banding pattern that is CLEARLY visible
3. The 3D only works well the the object that is in focus (IMO) the parts of the image that are blurry and to the sides of the screen actually lose their "3D-ness" and you get image separation.
4. The creators of the movie realise that they are making a movie for 3D and many of them add extra parts to scenes ( and some scenes entirely) just to show of the 3D effect. - Thank you Tim Burton, you used to be cool.
5. I already have the ability to look at a 2D image and can see "perspective" and can judge distance by things overlapping and relative size. We conquered this in visual arts some time ago. These concepts were partially used by Egyptian artists and then we mastered it in the Renaissance (thanks Brunelleschi).
6. Hollywood is after easy money and is quickly running out of ideas, (Transformers 4: Prime vs GIJoe and Whinnie the Pooh) and the use of 3D is just lipstick on a pig. How about you make films that are worth watching without the use of performance enhancing apparell??
I think that might be enough ranting for the moment. Do you get the picture though?

The day I buy a 3D television will be the day when I sell all of my audio gear for a new "3D, 7.1, Dolby-Braille" machine.
