As an art form, of course it's better to make "good" films as opposed to profitable films. Profit is genuinely holding art back, a lot of original ideas will never see the light of day because studios don't want to take the risk.

Why aren't good movies making more money? Why are shitty films making so much dough?

Because contrary to what online movie geniuses believe, a lot of people really do enjoy the media that's considered "lesser". Transformers, The Big Bang Theory, Twilight, etc. are all beloved among general audiences. Not everybody is looking for some deep, quiet, three hour film, they mostly just want to be entertained for two hours.

I'm not saying there's anything wrong with enjoying so called "lesser art", considering art is subjective and all that, but I do really believe money is doing more harm than good for film.
