The twins (4) are watching Scooby Doo with some enthusiasm. I remember watching Scooby when I was a kid, so these must be new episodes.
I used to like it, I must admit, although there is no logical reason for that. I also found Velma strangely attractive. Not sure if it’s her short skirt or brains.
There is really no variation to the Scooby plot.
He eats a lot, gets chased by monsters and foils them. It never changes.
Apparently there have been three Scooby movies. I haven’t seen them, but I can probably guess what happens.
