The lack of direction of Carver's Era, basically.

- He built up tablets and we ended up dropping them in Season 8 (and they weren't that exciting anyway).

- He built up Naomi to be a different class of angel and we got squat.

- He built up the idea of Crowley becoming human and relatable, at the same time when Abaddon was being built-up to be the new badass femme fatale leader of hell. We all know where that went.

As opposed to the first two showrunners where there seemed to be an end-goal to link their seasons and wrap them up together, Carver seems to be just churning endless subplot after subplot, and trying to see which sticks.

Just look at the summary/synopsis of ever era--Kirpke deals with apocalypse and heaven and hell, while Gamble dealt with purgatory and the power vacuum. Carver dealt with--???? Instead of picturing a general end-game to tie seasons together, he had more of a cause-and-effect approach, which, while present in previous seasons, did not seem to have an overall underlying theme/motiff.

The previous two had natural progression that made the story bearable.

Kirpke had MOTW > demons > high-tier demons + sam being demonic > angels + dean being angelic > archangels

Gamble had freak monsters > Alphas + ancient and powerful monsters (i.e., Dragons, Eleanor Visyak) + new and hybrid monsters (Khan Worm + Jefferson Starships) > Eve > Leviathans

Carver had tablets > prophet out of nowhere? + men of letters + knight of hell > more civil war > grand coven of witches out of nowhere + cain > The darkness all of a sudden?

Like what the hell are you on, Carver? Seriously. I would buy the Darkness arc if it wasn't for all the stupid pointless filler crap in between. You could take out huge chunks of Season 8 and 9 and nothing of value would be lost. They just happened for the sake of happening with little relation to what is currently going on.

Carver also had so much stupid retcons that totally botched the whole story if one is to take a look at the series as a whole. Reapers = Angels alone udnermines 5(!!!) seasons' worth of universe building and lore development. I'm pretty sure by now people are aware of what this entails I'm not even going to delve into it. It's just ridiculous and makes several subplots in the first five seasons laughable in retrospect if you accept the retcon.

Not only does Carver retcon previous showrunners' lores, he also retcons himself. Abaddon was shown to be almost unstoppable and somehow every appearance of her she seems depowered. They also kept changing Abaddon and Josie Sands' backstory. They also have confusing lore development (i.e., Knight of Hells having a sigil that predates Enochian--the language of an entire species that predated ANY demon).

Metatron was just painfully unbearable as a big bad.

'Angel radio' becoming a literal 'radio' demons could tap into using human technology surveillance. Really?

Angels suddenly appearing as white smoke/grace as opposed to the expansive blinding light that was a great contrast to the suffocating black smoke of demons.
