A fairly standard overpowered protagonist show, Tensei Shitara Slime Datta Ken’s defining feature is that almost everyone’s either extremely nice/reasonable or becomes so after being defeated in some manner (whether it be through force, conversation, or trickery). It’s very much a ‘sit back and enjoy yourself’ kind of production without much in the way of nuance or depth to get bogged down on; even the ecchi elements are practically wholesome when compared to what you normally find in harem series.
DanMachi’s second season on the other hand is very much not a ‘sit back and enjoy’ type of show, infested as it is with manufactured drama and asshole antagonists. A large number of storytellers get stuck between crafting the start of their story and concluding it, generally either because they get lost/sidetracked along the way or get greedy with early success and want to drag things out as long as possible. This appears to be a case of the latter.
None of these three arcs advance the various plot threads introduced by the prequel, and each features new antagonists whose only apparent purpose is to be defeated in random ways (likely to never be seen again). Not helping matters is that the action scenes are notably lacking… something. I’m not sure what exactly, just that they don’t match up favorably to earlier ones. Much like this season as a whole.
