No one wants to fight you on something so silly.
It's a good film by any measure - cinema is either art or entertainment. Sometimes it's both, but it doesn't have to be. If it doesn't match whatever standards you've devised for yourself then...cool.
What is art to one person is not to another. What entertains one person bores another. It's subjective.
If you want to fight people on this point, you're either very young or insufferable to be around.
