If you care for the plot, it's the same as every other Elvis Presley movie ever made. A talented small town kid rises to fame and fortune after being discovered by the industry. Half an hour into the film we're introduced to the kid's romantic interest, which develops in parallel to the advancement of the kid's music career; later, of course, there's a bit of a skirmish in that front, until everything turns out well in the end. Yawn.
Having said this, the music is good, and Presley's on-stage performances look like ... Presley's on-stage performances, which is to say they are fun. The characters are extremely formulaic, but the acting is decent. But the best thing of all is the Technicolor, which looks just gorgeous. All in all, as far as Elvis Presley formula movies go, this is a decent one.
