Its just a fun show. It has huge plot holes if you think too hard after the fact, but it moves at such a fast pace that it doesn't really matter. It has manic energy and joy, and some bits that are really quite dark (especially because it is a kid's show).
Maybe it helps if its something that you grew up with, but it seems to be a show that you either like or you don't. I don't think a lot of people are ambivalent towards it. To me the dodgy FX are part of the charm, they don't get in the way and they really aren't what the show is about.
