I feel the same way. It's full of plots that go nowhere or patently don't work (I'm looking at you, literally anything from Tara and pretty much all of last season), or tossing a million plot twists that go nowhere and have no point except a half a second of thrill. Not that the thrill works, because this show has solidly established no one of any importance is gonna die ever anyways (even though half the characters have been relegated to useless side plots for ages and barely even have contact with the main cast, and so basically serve zero purpose). Then, mixed in with all these patently absurd and insane plots is a kind of static romantic dithering that doesn't feel compelling because the characters and their conflicts never really change or evolve, and after a point it's all just character X hooks up with character Y and then people are upset about it for a while. It really compounds how out of hand the show is to think that, from the main character's perspective, she's know most of the other main characters for around one month (and, in that course of time, has fallen in and out of love with at least two of them).
The show does have a whole lot of eye-candy, I suppose, and maybe two or three characters I still enjoy, but that's really about all.
It takes quite a lot for me to ditch a show (more than it should if I'm being honest), but this show is probably gonna join Heroes on my wall of "I just can't do it anymore" fame.
