Great ending to end a great show! To be fairly honest, I didn't like how the writers made Walter into a superior super genius in the ending show. The series finale was somewhat predictable. All in all, I really enjoyed it.
The last scene was emotional. Walter's last moment was in a meth lab. As evil as it may be, Walter stated that he enjoyed cooking meth because it was great at it. People respected him and he had power. It was where he thought he belonged.
People will die for money.
