Metacritic reviews

Robin Williams is such a great comic virtuoso that it can almost hurt to see him straining to pump life into a conventional, uninspired, sometimes-goofy big-studio comedy such as RV.

A family-friendly comedy with some gut-shaking chuckles and a heartwarming message. Sadly, it's also a fine example of what happens when talented people settle for utter mediocrity.

The biggest disappointment is the rigorously rote nature of the characters and story line in Geoff Rodkey's script

In RV, the downwardly spiraling career trajectories of Robin Williams and director Barry Sonnenfeld intertwine like the ropes of a tangled parachute, and all the helpless viewer can do is look on aghast as the whole abortive fiasco plummets toward Earth.

Why did director Barry Sonnenfeld take on this project? Just to sully a fine comedic resume that includes "The Addams Family" and "Get Shorty"? And one last one: Which one of these levers do you push to send the RV careering off the mountain for good?

The bedraggled movie limps along to its phony hogwash of an ending, adding the ignominy of sentimentality to its previous sin of being so derivative.

Nowadays no family movie is complete without a values-oriented agenda and a bountiful supply of fecal matter, and RV supplies both.

Apart from a funny turn by "Arrested Development's" Will Arnett as Williams' evil boss, nobody appears to be having a good time. And the feeling is infectious.

Unfunny, sappy and massively predictable.

On those rare occasions when RV stumbles across a comedic moment that is legitimately funny, it drains the humor out of it by milking it dry.
