I had previously typed a whole lot of information about this anime, but then I clicked outside of the box. Ho-hum.
This animation was awesome.
Plot was good, but had a dull beginning.
Characters were cool. Liked Hoshino best. None of the characters were unlikable.
Art was awful. Actually, it was fantastic. But that character design….
Symbolism was present and the impact was felt. Good work!
The ending was just enough of a cop out to be considered a cop out, but felt like a necessity. At least they played it out well.
The friendship between Hoshino and Tsukimoto made me feel like crying. Ping Pong is powerful.
Loved this anime. It just had some dull moments and fairly crappy character design. There was also a plot hole with the final few episodes, but it might just add to the “Hero” persona that Hoshino had made for himself, so it might be justified… maybe.

If you really lost a text you typed, install the add-on Lazarus to recover lost forms! It saved my life more than once.
The plot had a dull beginning but I enjoyed every second of the first episodes. The animation of the table tennis players was so engaging the show might as well have been just about the sport and I would have loved it. The character design is misshapen, but I think it gives animators the freedom to animate complex table tennis moves without having to mind anatomy and shadowing, as well as easily use tilted angles. Yeah, it’s kind of a trade-off, but the result is largely positive as far as I’m concerned.
