The comparison of The Dark Knight to Le Clown Sobbing (a fictional movie that represents critically acclaimed, but unpopular movies) is ill conceived. Dark Knight received critical acclaim and is popular.
I think a comparison that is more fitting would be (though, neither can really fit in to any category all of the time- for example Wii Sports' reception has soured over the years from the hardcore critics):
High brow: Il Postino, Bottle Rocket (Wes Anderson comedies in general)
Good reception all around: Dark Knight, Titanic, Forrest Gump
Pop: Shrek 3, Terminator 3, Vin Diesel Movies
Crap: Stuff that fails critically and commercially.
Hard Core/High Brow: So many that I can't think of a specific one right now.
Good reception all around: Halo series, Mario Kart, MGS, Final Fantasy, Call of Duty
Pop: Wii Sports, Generic FPS that sell 500k+, Madden (again, Madden and Wii Sports get good reviews but then the critics bitch about it all year), Carnival Games
Crap: Imagine Babyz.
I would cite regulation, but I know you will simply ignore it.
