Slam Dunk just really does everything reasonably well. It doesn't really do anything fantastic in my opinion, but the sports scenes are good, I enjoy the characters, the humor is solid. This is just a very very solid anime.
In my opinion, if this anime was made this year, it'd probably be amazing. The fact that it has the really old style animation and just feels old depresses the score a bit, but this is definitely a solid watch.
