Well a few years ago I was apart of a group and one of the guys aunt's owned a theater so we used to have some pretty good cams. But now a days cams are awful, you can see people getting up for more popcorn, the camera is always bouncing around ect.
Cams aren't what they used to be.
I'll only watch one if I really want to see the movie and can't make it to the theater. But sometimes they just wreck the movie in my opinion. I've seen a cam and hated the movie but when I watched it on dvd I thought it was alright because I wasn't getting angry at people moving around.
