I watched this as a kid when it aired, so some parts are cloudy in my memory. Skimmed through two episodes as a refresher.
Story is okay, typical Ash stuff like "oh i gotta do all of these and then ill be a pokemon master!"
Art was good, although it doesn't look as good as I remember. 2010, so I can't really hate on it.
The sound was to an extent good quality. Not the best, as it was aired on Cartoon Network in the early 2010s, lol.
Characters are a six because they aren't as well written as other anime of the time, probably translation errors as well but I'm not sure.
I enjoyed it at a mediocre level, as even though kids have short attention spans, it caught mine.
