Grade: B | Valentine’s Day came and went, but same-day release “Music and Lyrics” left something behind after the cards and chocolates were done.

Mostly, what is a left behind are a lot of Hugh Grant one-liners, a happy ending and some catchy pop music. But the movie, spanning only a week’s time, plays out well enough to introduce the characters, showing them writing a hit song and performing it.

Drew Barrymore acts well as a neurotic writer-type. Grant is well-cast as his usual witty self, (Barrymore: “That is incredibly sensitive from a man who wears such tight pants.” / Grant: “It forces all the blood to my heart.”), and the chemistry between the two is fine and warm-hearted. The movie transcends usual “rom-com” status by bringing in could-be-cliché pop diva Cora, played by new actress Haley Bennet. The film treats her not as an airhead, but with some real discretion, despite giving her lines like, “I want to show you the roof. It’s upstairs.”

There are vague points brought up throughout the film concerning integrity versus accessibility, the emotional impact of melody versus words or how a person may be impacted by expectations. Yes, these are not standard questions discussed in a light romantic comedy. But, there isn’t anything to worry about, as the majority of the movie is lightly laughable jokes and toe-tapping music. Viewers probably won’t recognize the author of most of the songs in “Music and Lyrics,” but it is none other than Adam Schlesinger, the man behind “That Thing You Do.”

Grant’s fictional 1980s group, Pop!, is easily comparable to the real-life ’80s group, Wham!, featuring George Michael, though the plot is entirely fabricated. However, the music video for “Pop Goes My Heart” looks authentically ’80s, even if it’s not the most fun part of the movie.

A major discussion in the movie is that a good pop song (or, in this case, music video) can make people feel better in 30 seconds than any thought provoking piece of heavy culture can. Barrymore and Grant call it the debate between “dinner and dessert.”

“Music and Lyrics,” like the music and lyrics inside the movie world, straddles that line between dinner and dessert perfectly, unless you’re one of those who just wants to start with ice cream.
