I got 3 episodes into Gavv and I didn't continue because it was clearly really, really stupid. I know this is about a gummy-powered superhero and that I'm not supposed to take it seriously, but it's still disappointing. Instead I'm watching Den-O, and it's pretty good. The sword, rod, and gun forms are really cool, and it's great whenever the DenLiner battles. It really scratches the Metal Hero itch. I appreciate that they use bikes as much as possible. The story is also surprisingly good; despite being similar to Orguss and having many more constraints, the quality is unbelievably higher. It's also a lot better than Faiz's story despite being comedic and lighthearted. Faiz was very predictable and had Death Note-tier overexplaining, but Den-O doesn't, so it's better. Lots of the "character drama" seems to have more of a purpose in Den-O so they can get to the right time.
