The Nostalgia Critic discussed this. He mentioned that professional critics have to watch more movies than the average moviegoer, so they're more likely to notice the cliches and beats that movie markers rely on.

The average moviegoer, however, would likely get swept up in simple crowd pleasing movies more easily.
