I remember the Scooby Doo of when I was a kid. It was full of ghosts and ghouls, but at the end of every episode it turned out to be robots, and masks, and projectors.
There's a newer Scooby Doo series. It's all the same characters, with virtually the same voices and the same designs. The drawings look a little cleaner and more modern. The main difference is the universe it takes place in. Where the original Scooby Doo was in a universe full of pranksters and hoaksters, but no real ghosts. In the new series, though, there are witches, aleins, ghosts, and anything else you can think of. It's enough to make Velma hang up her glasses.
