Whats your rules on dropping a series?
Personally my rule is to never drop a series no matter how tortured I am watching it. Black Rock Shooter and Texhnolyze come to mind. The reason I never drop a series is so I can properly complain about it later. Also you never know it could redeem itself, a recent one I watched that did exactly that was Phantom: Requiem for the Phantom. Took quite a while, but it did.
