Only good thing that came of a sketch comedy movie was Waynes World, and that includes both of them... God bless those two.
There's really much better examples to support your argument.... of course, most people don't know they were ever made because they suck so bad... Try these on for size:
"Stuart Saves His Family"
"It's Pat"
Of course, as good as Wayne's World is, it's not the best SNL movie. Let's not forget about Blues Brothers. Of course, let's not remember the sequel.
