Oddly enough I thought last week's premiere was a very weak episode. Beyond the Denny's opening, the episode just didn't bear much weight in its plot line. Season four wrapped up with a bow: Walt brilliantly murders a major drug lord, finally giving Hank his 'Heisenberg', and eventually stands to become the sole meth kingpin in the ABQ and beyond. With that said, why go backwards by devoting an episode to magnetism? This ain't Mythbusters. Clearly, Hank's going to see the wreckage outside the evidence room and realize Heisenberg is still out there. Why not have Walt snatch the laptop last season and start fresh in season five?
Mike's return didn't add much either. Last season he was a cleaner/hitman/fixer, cold blooded and bad ass. Now, he's like a petulant little brother, trying to be the Debbie Downer instead of the hitman. Sure, he used to work for Gus but it always felt more like a job than a longstanding loyalty. A guy like Mike would respect the business end of Gus' killing and remove the emotion of the act.
Ted's still alive? Really?
Regardless, it's a tremendous show. I just didn't think that episode was very good. Magnets, bitch.
