This season of Breaking Bad is already better than S4 imo, and could surpass S3 depending on how things play out. If you just watch shows for action and twists, perhaps it's not for you. I think some of the writing has been ridiculous in terms of the various heists that have gone down (breaking into a police station, magnets, etc) but they sell it well enough to make you not dwell on the logistics. Also the emotional stuff has been amazing this season. Skylar's confrontations with Walt especially. Plus you can tell Hank is slowly, slowly putting the pieces together.
