Are many people not aware Curse of Chucky exists?

I've been reading some comments on the teaser trailer for Cult, and I've noticed a lot of people complaining that the series was ruined with Seed, so how are they gonna bring Chucky back now.
Um, there is a thing called Part 6, which did just that? Seriously, they should have released it in theaters, not straight to DVD because it's definitely not that well known.
