The original “Footloose” may have had an absurd premise and not even a tacit acknowledgement of the existence of people any color besides white, but it was an ’80s movie, after all. Its datedness — and director Herbert Ross’ great, toe-tapping title sequence — is part of its kitschy charm. The cast, too, was exceptionally winning: Kevin Bacon as the upturned-collar out-of-towner, a radiant Lori Singer as the rebellious preacher’s daughter, Chris Penn as the hayseed sidekick.
