But the main value was nostalgic; the parody wasn't all that good and the story was rather unfocused.
This. It was a great trip down memory lane for us old farts who were the target audience in the 70s and 80s. No, the story itself (or stories themselves) weren't memorable, for the most part; but the satire and parody of Saturday morning cartoons was a great blast.
I really loved the ending monologue about the cartoons being followed by 5 hours of golf. That was the best part because it was SO TRUE! Or that's how it felt. Noon was always a big disappointment - cartoons were over and the stuffy boring stuff filled the rest of the day.
