I ASSURE you that SNL skits have wider appeal than Monty Python, which really just appeals to a specific subset.
Maybe to Americans? Not for the ROW
As a non american SNL is 99.9% asinine crap and pales in comparison to Monty Python even after all this time. May be that's why it has a wider appeal but the formulaic lack of humor and fear of actually punching up comes down to the bitter old man in charge.
