Romantic comedy: low art?

I believe that most movies are enjoyed primarily because they offer the
viewer an escape from their mundane and normal lives. Whether a janitor
feels the rush of a heroic soldier, a sociopath gets to live out his
serial killer tendencies, or a spinster pretends that a charmingly
befuddled stud is waiting at the local coffee house to sweep her off her
feet, fantasy is the appeal of film. How then can you label romantic
comedy as the "low art" genre? So few movies that reach blockbuster
status actually teach,inspire, or otherwise utilize the sounding box
that is available to filmmakers. Isn't it then more positive to evoke
sentimentality rather than anger or fear, regardless or whether the
parameters are realistic or not? I personally would rather delude myself
for an hour and a half with schmaltz.
