I've 'finished' tv series or film series by reading the synopsis before, the show/film series it self was becoming dull or bad or whatever, but I still wanted to find out how it ends. Done the same with books too. Usually YA series that I didn't realise was a YA series when I started reading it. Only so many times you can read about a 14 year discovering they're special and then somehow they kick vastly more powerful, trained and skilled adult ass. Or the other variant in book 1 they're not special, and still win, but then in book 2 they become special and win because they're basically unkillable. Woo-hoo!
