The chance of a sequel being good is inversely proportional to the square of N where N is the entry that is currently being released.
Generally, I'd rather see sequels not happen. I think it's fine when you have a series that is too large for one game and which is planned with an over-arching story like in Mass Effect but churning out frequent sequels with no end in sight is what put me off the likes of Call of Duty and Assassin's Creed. Even for game I like, I usually groan at the thought of a sequel because I always think that the talented team who put the first game together could have been really creative and exciting with a new IP.
I have no problem with spiritual successor's though, it seems fine if you want to keep gameplay elements from one game to the next.
