So... jeez...
This season is really, really depressing. It feels like everything took a fairly substantial hit. Everything from the quality of the VO performances, to the pacing, to the sound design...
Season 2 is still enjoyable, but it is really hard to come from that first season to this one. The animation is also astonishingly bad. I was anticipating that it would be a downgrade, but I thought people were probably being a little hyperbolic. No. They weren't. If anything, people are being too generous. I have seen quite a few people claim that it is only bad in comparison to the first season; that isn't true at all. It is bad when compared to most mid-tier shonen.
It is good enough to keep watching, but it is hard to not feel aggressively disappointed.
Hey, guys. I don't think anyone answered your question. So, if you are still unaware, Tubi TV carries it. The app is free (though it has commercials) and is available for the PS4. Cheers!
