Movie sequels

Oh I don't know if I agree with ALL that. For the most part, maybe. I can name two really good movies series that to me were every bit as good or even better with sequals. Back to the Future and Lethal Weapon.The key is keeping all or most of the original cast. Also another good recent one The Expendables and The Expendables 2. Kitty and I thought both of those were really good.
