The one thing that pisses me off about harem and actually a lot of Japanese manga/anime is that they completely wimp out on picking a single girl (or guy) to win in the end. I'm okay if it's a harem ending, or they pull a School Days, but leaving things "open" pisses me off. At least SAO had the decency to say "yep this is canon OTP DEAL WITH IT".
i know Tenchi Universe pushes for Ryoko at the end; it's not definite or anything but it was close enough.
