The story is beyond terrible from what I hear, I haven't watched it myself so I'm saying that in advance. Unlike Frieren, I don't think Solo Leveling does anything we haven't seen before, & the characters & story sound extremely uninteresting. It's mostly just about the action it sounds like. Log Horizon, Overlord, lots of other things would be a better watch in that category. Or even that one where the guy has an amazon kiosk on demand in another world & can summon anything he wants to cook or eat, the animation quality in that one is great & the concept isn't taking itself seriously.
