All That Is Necessary for the Triumph of Evil Is for Robin Williams' RV to Top the BO List

Color me Dee Dee "I Don't Want to Live This Life (Anymore)" Ramone as the AP reports on the weekend's movie box office:

Audiences hit the road with Robin Williams as his family-vacation romp "RV" opened at No. 1 with $16.4 million, while the Sept. 11 drama "United 93" debuted with $11.6 million.

Yes, yes, I know that the customer is always right. Or at least that the audience has a mind of its own. And certainly that culture isn't something that needs to be good for you (god no). And that Robin Williams has been absolutely mesmerizing since he began playing only truly evil villains since his turn as the Josef Mengele of laughter-is-the-best-medicine advocates, Patch Adams. But still, when a zany, poorly reviewed knockoff of Vacation (itself nothing to write home about) tops a well-received 9/11 movie, well, it's cause for a sigh, innit?

Update: As several early-rising, mathematically competent commenters point out, United 93 opened in far fewer theaters than did RV. The former's per-screen take is $6,465 vs. $4,506 for RV. More details here.
