Full Screen or Wide Screen

When you're buying a movie and there are full screen and wide screen versions of it available, which do you pick? I always pick full screen when there is an option. If I'm watching a movie on a TV, I want to to use as much of the screen as possible. I really hate the black bars on top and bottom of all those widescreen movies.

Widescreen is my choice. Many of the full screen movies have content cut off on the sides of the screen. I would rather see the full picture in the original format, even if it is a little smaller.

Plus, with all the new TVs being widescreen, full screen is going to be a thing of the past. Some movies, like Pirates of the Caribbean 2 (or 3?) don't even get full screen releases now.
