I thought the end was interesting to say the least. You cant just take it at face value, it makes you think about what Walt is doing, it's a little too easy to relate to/with him sometimes but the reality of it is that he is doing some horrible shit. They could have made it more heavy handed and literal but I dont have a problem with them not having gone that route, if they did it would have been every other show out there.
Some of you guys have pretty low expectations it seems like, his motives arent that simple any more, theyre trying to create a really complex character, what they've done with this finale is serious raise expectations IMO.
The only problem I had overall with it is that they over did it with the teasers.
