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.
outside of shows that are intentionally anthologies, that sounds to me like OP’s fear of shows not only dragging on longer than they need to, but also endlessly dragging the viewer nowhere forever.
Yeah… I’ve definitely grown to enjoy shows that know they have to end and know what that ending is going to be instead of just dragging the corpses of all the characters through eternity.
I get wanting to watch a show forever, getting attached to characters and their antics (looking at you Red Dwarf) but its okay to let the characters and their stories fade into the sunset as it were.
