I like to give all anime a chance but sometimes that's impossible.

Midori Makibao is a small white mule with exceptional galloping speed but is too much of a wimp to really be a proper race horse, but after his mother is sold to pay debts and coming to understand his Mother's parting words, Makibao gains the courage to race.
To explain the bizarre art style, it's referred to as Gonk - to make a character deliberately ugly for comedic effect; that can work fine for a one off character but having a whole series with that style along with some utterly piss poor attempts at humour makes Midori no Makibao borderline unwatchable, I only say that because it does improve later on when Makibao races but getting through the early series is just painful.
No dub, it can stay in Japan.
Final Verdict: Kudos if you manage to sit through it long enough to get to the better parts but it's unfunny gross out humour along with it's hideous art style is just not worth the effort.
