While watching Dan Doh!! you realize, that you sit in front of your TV - mumbling the same phrases, over and over:" Doh I've seen that already! But in a much better way", "Doh, this character should seem cool, I guess!", "Now he is going to make some kind of intergalactic shoot which will hit! See I was right...".
Don't missunderstand me, if Dan Doh! would have been produced before: Hajime no Ippo, Prince of Tennis or Hikaru no Go. It would have been a "good" Anime. But even then, just good. There is nothing special it's getting boring to watch after a while and there is no real depth, or the wish to support the main character. The art is nothing special, the characters seem to be designed by some old fashioned guy, the whole picture is out of place. Some scenes where you are probably supposed to get excited - you just sit there and stare or even laugh... Well the only real reason to watch this anime would be that you are a golf maniac. But even then you probably won't be happy with it.
