Sorry, but that movie didn't deserve any Oscars. It was terrible, no matter how many people saw it. Popularity does not make a movie good.
Hmmmm...
You sound like a left wing elitist college professor who thinks most everyone lacks taste to know what a good movie is, that the third rate "art" movies nobody watches are the ones only sophisticated and liberal (of course) minds can appreciate.
Well here's another rating system that gets Hollywood's attention more that yours....how much money it makes. You see, the fairest arbiter of the quality of a movie is how many people want to see it. This system isn't subject to your snotty aristocracy, you stuck up Leftist friends deciding what a good movie is and giving awards to the most Leftist films regardless of whether people went to see it or not.
Passion of the Christ is a great film by the only standard that matters.
