Shrek Forever After'Shrek'? Shrug.

It seems perverse to call a box office victory stemming from a $71.3 million opening weekend a disappointment, but that's the only way to categorize the debut of 'Shrek Forever After.' Even with 3-D and IMAX surcharges, it fielded the weakest opening of the three 'Shrek' sequels and underperformed even the most pessimistic estimates. At least it didn't underwhelm as badly as this weekend's other new wide release, 'MacGruber,' which earned a well-below-expectations $4.1 million and failed to crack the top five.
