>What they do share is that the main character is an underdeveloped Mary Sue, without character flaws, without weaknesses they must overcome. They're just made awesome from the start. It probably stems from the inability of current Hollywood to portray female characters as having any weaknesses at all, that would be heresy. The result is that it's hard to empathize with and care about the main character. They don't have any dimensionality.

I agree. This seems obvious. So why can't these sophisticated critics see this and rate the movie accordingly? They're obviously using a completely different set of criteria to rate movies, and entertainment is far down the list.
