Yeah, i vividly remember the first three seasons aswell. From there on it is one big blur, couple of great characters along the way who were mostly killed off.
That scene in the finale was epic though ... never laughed so hard at anything. "That's JACK ... BAUER"
I look forward to the new one. Maybe they have freshened up a little. Also the setting is in London and they have Yvonne frickin' Strahovski on board!
