I'm the same. Don't care about spoilers. If a story is only riding on surprise then it doesn't have much to offer in the first place.
Even with series, if it has loads of seasons; when it outlives its usefulness then I have no problem ditching it after a number of seasons if I feel it has jumped the shark.
Such exquisite poetry, I've seldom heard before. I'm going to get this comment printed and framed.
