Jennifer Aniston is back on the big screen Friday in the comedy Office Christmas Party.

But most critics agree that like most office Christmas parties, the expectation doesn't match the reality.

The film that re-teams Aniston with her The Switch co-star Justin Bateman gets a squashed green thumbs down on RottenTomatoes.com , registering just 44 percent on the websites Tomatometer.

'This party is a dud,' wrote Calvin Wilson of the St. Louis Post-Dispatch
