Some nice, smooth, consistent quality. Better Call Saul was in my opinion pretty consistent. Single season anime is almost always consistent, like My Dress-Up Darling or Terror in Resonance.
Not dragging on longer than the series needs to seems to be a key point.
Some old ones from Amazon, when it was good :
Halt and catch fire Mr robot Red Oaks
Random others
Vice the deuce Line of duty Responder Tabboo North water
Some are mini series .
