3D has a lot of disadvantages. Most of the movies are post-converted, meaning the 3D is fake in many areas (visual effects are real 3D though), and also english isn't my native language, which means I need subtitles. I can watch a movie without subtitles and still understand 95%, I've became very good at understanding, but I also like to watch movies with friends, which means subtitles are obligatory and with 3D movies and the .srt files in can become a little messy. I'm towards the 46'' right now, unless some 3D defender comes along to give their own valid arguments!
