I'd be okay with a two-tiered system: a Netflix Light that is cheap and ad-supported (hopefully at the beginning, not interspersed throughout), and a Netflix Full that offers no ads.
Mostly though, I just want to have a decent selection in Canada. I was chatting with a friend about the possibility of doing a movie streaming startup, and I couldn't get past the fact that Netflix's biggest problems are not of their creation; they come from the studios. I wish them the best of luck, and hope that someday I might be a customer, but I'd hate to have to deal with the rights hassles that they do.
