"Lupin" debuted on Netflix's popularity rankings this week but couldn't top "Bridgerton." Netflix introduced daily top lists of the most popular titles on the streaming service in February. Streaming search engine Reelgood keeps track of the lists and provides Business Insider with a rundown of the week's most popular TV shows on Netflix. Netflix 's new French series "Lupin" debuted last week to critical acclaim, and now it's one of Netflix's most popular titles. But it couldn't beat Shonda Rhimes' first Netflix series, "Bridgerton," or the "Karate Kid" sequel series, "Cobra Kai," which recently debuted its first true Netflix original season.
