I’m not crazy about the jukebox musical as a genre. But, you know, sometimes it depends what’s on the jukebox.
Take “Million Dollar Quartet,’’ which has arrived in Boston for a run that ends Oct. 20. It has all the weaknesses of the genre: a wafer-thin story line, minimal-to-nonexistent character development, stilted dialogue that acts as little more than an expository bridge to the next song. Essentially, it’s a concert masquerading as a musical.
