(Entertainment Weekly) -- It was a glass half-full, glass half-empty kind of weekend at the box office for "Funny People," writer-director Judd Apatow's comedic meditation on fame, humor, life, and death. Adam Sandler and Seth Rogen star in "Funny People," which took the No. 1 slot at the box office this weekend. According to figures from Hollywood.com Box Office, it opened at the top spot with an estimated $23.4 million, better than Apatow's The 40 Year-Old Virgin ($21.4 million) -- hence, the glass is half full. But that figure is far lower than the debut for Apatow's "Knocked Up" ($30.7 million), and it's the worst opening for a comedy for star Adam Sander since his 2000 turkey "Little Nicky" -- hence, the glass is half empty.
