The animation wasn't that good, but it was still very funny. The best part is probably how it holds up much better than other 2000 cartoons. I'm glad it didn't get too graphic. You really do put this together well. Yeah, I remember everyone saying Shaggy and/or Scooby were stoned. The creators said this was in no way their intention.
Of course, him being high would explain why Scooby could talk. I mean, the supernatural was always fake yet they had a talking dog. He wasn't really a talking dog, it was just Shaggy being high! We've had far more graphic stuff nowadays. This seemed to be ahead of its time.
