Ao Ashi was good. Not great, but good. It's simple and follows the main tropes of a sports anime. A hereto unknown, hyper-skilled, especially positive [soccer] savant is plucked from the sticks to play ball in the big city. That being said I don't hate any of those at all. I haven't watched enough for those commonalities to have gone stale. Like I have said in previous sports anime reviews, you don't have to reinvent the wheel as long as it's fun and entertaining.
I liked the art style. Simple, not especially over-stylized, nothing special, it feels comfortable. The animation of action and movement isn't great, they don't do anything special, but they also don't overly rely on voice-overs on still images. The characters are mostly uninspiring. The main cast are filled with characters you've seen before, especially the main character, Aoi, who is basically a carbon copy of Sawamura Eijun from Ace of the Diamond. The characters I find the most interesting are Togashi and some of the players from the A-team who we don't know yet. That's not to say I dislike any of the other characters. Like most sports shows, there are few female characters, all of whom (with perhaps one or two exceptions) are defined by their relationship with men, specifically our MC. Would be nice to see a sports anime with more dynamic female characters, I guess it's also on me for not searching those out lol. I thought the first set of OP and ED were good enough, but that being said I don't really remember them.
I liked this show, I really did, but the more I talk about it the more I consider it a lower rating. It watches really quickly, it drew me in to where I wanted to keep watching past my bedtime. If you're looking for a show to watch in a few weeks or while figuring what to watch next this is as good a show as any.
