Loved the final appearance of Badger and Skinny Pete. Loved the whole Grey Matter bit. Loved Walts final goodbye to his family. Loved how Walt got Lydia with the ricin.
But JFC, that ending at the meth lab rough ridin' sucked. What a bullshit ending. So let's see: not only is Walt a brilliant chemist, he's also a brilliant mechanical engineer who just whips up this amazing rotating gizmo mounted in the trunk of his car (holy mcguyver), then the entire rough ridin' crew except Todd is too stupid to duck as it slowly pans through the living room. Srsly? That's the best ending they could cook up? Sad way to end the show.
