“Bohemian Rhapsody,” the song by Queen, lasts nearly six minutes, a very long time for a pop single back in 1975. A baroque blend of gibberish, mysticism and melodrama, the track is a can of earworms, one of those musical confections that get into your head whether you like it or not and stay there forever. Some of us who were devoted radio listeners in the mid-’70s will surely sit up in our death beds and whisper “Galileo, Galileo, Figaro” with our final breaths.

“Bohemian Rhapsody,” the movie about Queen, lasts more than two hours, not a very long time by modern feature standards, even though it feels interminable. A baroque blend of gibberish, mysticism and melodrama, the film seems engineered to be as unmemorable as possible, with the exception of the prosthetic teeth worn by the lead actor, Rami Malek, who plays Freddie Mercury, Queen’s lead singer. Those choppers may give you nightmares. And some of you who venture into the theater will surely be inspired to exclaim “Mama mia, let me go!”
