The "Dead Zone" television series started off really, really cool.
Then... it started to drag.
Yeah yeah yeah there's been a few wicked twists here and there. They even took out a primary and changed the chemistry of the cast a touch.
But in the end, I gave up watching it.
I kept thinking "Get on with it! Let's drop the gloves and finish this sucker!"
"Nip/Tuck" got to that point. Even though the writers kept throwing the characters at each other in deeper and deeper pits of depravity and evil, at some point you start to wonder at what point does someone pick up a scar that doesn't heal?
Sure, the supporting cast gets mown down every season, but there comes a point at which a primary needs to go down. Hard.
Maybe I've gotten to the point where I can't deal with watching an arc-based series in series. I need to watch as a marathon session.
