The music in "Help" is today infrequently played by radio stations, even those still giving significant exposure to Beatle tunes. However, it is--like all of the groups' music--terrific. "Another Girl, Hide Your Love Away, Ticket to Ride," etc.
See "Help" again (or for the first time), listen to the music carefully and compare it to the garbage being aired today, and you'll realize why the Beatles are the best all-around popular group there's ever been, and most likely will ever be.
The movie's plot is secondary.
