Star Wars: The franchise where the movies that had characters speaking vernacular English (like Han Solo) were much more highly-regarded than its movies that almost exclusively featured characters speaking prescriptivist English (Episodes I, II, and III).

You can diss it all you want, but the Abrams series brought Star Trek back from the dead and brought in a huge new audience base that's still with the show today.
