I agree. I never understood the hype around Kaito Kid.
Don't get me wrong, he's a fun character. I don't hate him, but I never LOVED him either.
Actually, when I first started watching the show (I was about 4 or 5) I remember being incredibly confused about who he was, what he was doing and why he was doing it. It's not until now that I'm actually starting to figure out who he is.
So even from back then, to me, he was just a really weird guy.
Well, right now I'm actually reading the manga for the first time, so maybe once I'm done I'll be converted too. But for now, he seems a bit overrated...
