I thought last season was amazing but the last couple episodes I've seen have been beyond fantastic. It's all tying together. All the crap from the very first episode in season 1 and hitting all the major plot points throughout the show. The death of Terry, the Armenian money train, Asaveda's blowjob moment, everything! It's like seeing some master author weave together all the disparate plot points for one great all-encompasing climax.
For some inexplicable reason, the French are actually seeing the show earlier than the US audience and with 2 episodes showing a week. I've been bittorrenting the lot of them and that means I'm around 4 eps ahead right now. I just watched #9 and it's fan-freaking-tastic.
