We need to get better as a species at pretending certain seasons didn’t happen. Season 5 of The Wire, Season 3 of Homeland, anything after All Along the Watchtower in BSG etc
The thing about season 5 is that it doesn't stand up well to the other seasons, but it does stand up reasonably to most other television; I'm not sure it's quite in this category.
I like the last season. I thought it was a comic masterpiece (darkly comic) and a master class in all sorts of irony. Maybe that's the rub. Still, these two scenes are gems:
One of the main writers left before season 5, which might explain it.
It's disappointing, because the season's focus on journalism and public optics was really interesting and educational and in many ways well-executed. But the serial murder stuff just made it kind of goofy.
Seasons 1 - 4 are so good that it's not a big deal, but it seems so rare that multi-season shows stick a graceful landing.
Keep going beyond the second season, it gets better, when the lines between the gangs and the government blur
