Funny thing is that in 1998, 5 of my friends dared me to watch a Scooby Doo marathon for all 24 hours, I did and they gave me 1,000 bucks (200 each). That was when I was 21 years old.
Same here.
Hanna-Barbera has overused Scooby-Doo to the point that it's become tiresome. Now when I watch Hanna-Barbera, I mostly like to see The Flintstones and The Jetsons (and also Jetsons: The Movie).
Overused, in what way?
Scooby Doo has been over shown. As a kid, I used to love it, but stations like CN seemed to show it way too much. That's how it's "overused", imo, and which is why I can't bring myself to watch it now.
