That is up to you. Personally, I prefer films in 2D because the glasses are really uncomfortable.
3d movies are rated just like non-3d movies.
Definitely
The ones that they give you.
The new movie Step Up 3 has two versions, a regular one and a 3D one. To watch the 3D version, you need the 3D glasses. If you're watch the regular non-3D version, you don't need the glasses.
If you have passive 3D TV then yes you can watch Avatar 3D with its passive 3D glasses.
The only animation you can watch in 3D are the feature films that were created in 3D and released on 3D bluray.
No. Step Up 3D can also be in 2D. Watching a movie in 3D might cause $20 more than if the movie's not in 3D, but they should also have a non-3D version at the theatres.
Yes, they make 3D televisions, and you can buy Blu-Rays with 3D versions to watch on them.
I can't imagine you can. You can only watch 3D programming on a specified 3D channel on your cable/satellite service, so there would be no need to disable it. So essentially, if you don't want to watch 3D, don't watch the channel.
Any 3D movie requires the correct glasses to watch it, so yes.
To watch a 3D movie, you need a television that supports 3D graphics (and the 3D glasses that come with it). You also need to have a DVD/Blu-Ray set that supports 3D.
That depends on how young they are. Children under 6 shouldn't really watch 3D and an adult should supervise children over 6 when watching 3D. You should also know that active 3D TVs like those from Samsung or Sony are more likely to cause headaches, eyestrains and dizziness. They use shutter glass 3D technology which can give a lot of stress to kids' eyes. If you're going to let your kids watch 3D, they should watch a passive 3D TV rather than an active 3D TV. Passive 3D TVs use lightweight 3D glasses that use different technology than shutter glass tech. I have a LG Cinema 3D TV and I don't worry too much about my kids watching it because it's flicker free and doesn't make the kids dizzy and not bad for the eyes because they use passive 3D glasses.
