Rokudenashi = crap
Shuumatsu nani = crap
Sword Oratoria = meh
zero kara = meh
subpar season...
I'm pretty much watching all four of those, and I don't think I'd say they are
that bad, but they're definitely not great either. I was a bit interested in SukaSukaSuka, but after the three came back from the mission, I got a bit bored with it. Rokudenashi... has some decent moments, but my god, its lows are
bad. I really couldn't stand all the happy-go-lucky crap between the three girls as it felt like the most generic, boring fluff. Oh, and I don't care if the show revealed why she's called that, but Re=L is the dumbest name I've seen in anime so far.
Zero Kara isn't too bad, but it meanders way too much. Sword Oratoria still suffers from what we've talked about earlier. Leyfelia (the elf girl) is pretty much an insufferable, annoying character. It reminded me a lot of Railgun, which also had the weird, obsessive female character, but the difference is that Railgun doesn't put nearly as much focus on that character. In Sword Oratoria, the anime puts way too much focus on Leyfelia where you can easily get half or more of an episode dedicated to her huffing and puffing about Bell dominating Aiz's time.
Although, I do agree that this season isn't very good. It probably doesn't help that I read Boku no Hero Academia instead of watching the anime. On that note, I do think that manga has gotten a bit meh with this latest arc. It's usually not a good thing if I prefer the monthly side-series Vigilantes to the main series.
