Yeah i've heard the same thing. It's become very mainstream so it's going to be packed with people. Even though there are a lot of famous producers, directors and actors there, like directorik said, you would have to compete with a lot of people to get the right person's attention. Smaller film fests are much more intimate and less elitist. Plus, if you want to see the short films from Sundance, you can always watch them from their website.
