There's no greater evidence to that than "Scooby-Doo and the Reluctant Werewolf." The main story doesn't seem like it could fit a standard Scooby-Doo episode slot, so it somehow turns into a road race. And I swear it did because they had a Wacky Races "movie" concept and partially written script that wasn't considered strong enough for a full 90 minute telefilm. And even then the road race drags into filler. Repetitive monster puns about the cars overtaking each other make up the last over a half hour of the film, and it gets tiresome after the third time.
It's not a bad film, just one that should have been a half hour shorter.
