BNA is pretty good, I love the main character who's a tanuki. If you're a fan of trigger anime, it basically has that kind of vibe like Gurren Lagann. I've only watched the first 3 episodes.. so I can't say much more of it XD
I have heard that Voltron did went a lil wonky at the end, I kind of avoided watching it since the fandom went out of control and it has to be something I watch alone as my housemates are not a huge fan of it rip
