I definitely enjoyed the first Avatar, but I honestly can't imagine the need for 2-3 sequels.
Kind of feels like the Matrix where the first does the job and gives you a taste of what could happen.
I'd agree with that. The first one was good and I own it on blu but I'm not sure we need 3 more sequels. I could see making one more for giggles (which I'd see just for the sake of seeing) but after that it seems like going to the well just because we can.
