Their first actual slop game is ER Nightreign. Original ER was merely setting the foothold for it, but was not quite there yet, maybe just a few bosses. Ultimately, the game was still about exploration first and foremost.
But all in all, Souls-like had a decent start with DS, but was still trying to find its way and understand what it wants to be. DS I and DS II were those exploration phases. Then went on to solidify the formula with DS III, made a few side steps with Bloodborne and Sekiro, peaking with the latter. Then culminated their chosen formula with ER and then it kind of just became redundant. ER is how they wanted all DS games to play like, so there is not much to improve from here and they just started making bosses more flashy and spectacular, which is what we see in new ER now.
Sekiro is still their best game.
