With Labor Day approaching, it’s time for entertainment pundits to pontificate about the summer box office season. Today, the LA Times provides a studio-by-studio analysis and at the top of the heap surprisingly is not Warner Bros., despite The Dark Knight’s $490M effort domestically, but Paramount:

No other studio claimed more than one movie grossing more than $200 million this summer, and Paramount had three: “Iron Man,” ” Kung Fu Panda” and ” Indiana Jones and the Kingdom of the Crystal Skull.”

At the bottom of the heap, as noted previously, 20th Century Fox. And not only horrible box office results, but also just plain bad movies — Space Chimps, Meet Dave, Mirrors, Babylon A.D.:

Fox’s highest score on Rotten Tomatoes — an online review aggregator that is part of News Corp.’s media empire — was delivered by the gone-in-a-flash “The Rocker,” which posted a measly 37% positive average score.

Ouch!
