Why is there a U.K. version of ‘Saturday Night Live’? And is it any good?

“Saturday Night Live” did not produce a new episode last week from New York’s Studio 8H — but it’s likely creator Lorne Michaels had a lot on his hands anyway. On Saturday, former SNL cast member and comedy royalty Tina Fey hosted the premiere of “Saturday Night Live UK,” a London-based spin-off of the 51-year-old U.S. series.
