100% agree. Was saying the same thing to my coworker this morning. Gus Fring took the show to heights that will now be impossible achieve. Not only because of how compelling the character was as a villain, but mostly because of the nature of the audience's relationship with Walt. Walt's humanity died in his crawl space and ever since, he's been impossible to root for, so the emotional stakes of the show become less traditionally antagonist v protagonist and more a voyeuristic relationship where the shock value and drama of the show have more to do with the depths that Walt has and will continue to sink.
Specifics dealing with last night:
For all the theories of how the show has built into a story where Hank is the hero at the end, we've actually spent very little time with his this season. The tension in his office where Walt was removing the bug was a beautiful bait and switch where I thought he was going to catch Walt, but where the tension arose was from Walt overhearing that the lawyer was going to turn on Mike. They even left it ambiguous to the point where we don't actually hear Gomez mention that it's his lawyer, so there was a minute or two where I thought that Walt would assume it was Jesse who flipped. That's a perfect example where the show has gone to remain compelling despite no real hero to root for and I love it, but it's just not capable of reaching the same thrilling emotional roller coaster that we had in the last two seasons.
That is perfectly stated.
