The ad line for RV states: "On a family vacation, no one can hear you scream." You won't exactly hear anyone screaming with laughter in theaters, either. Robin Williams does the same frighteningly hyperactive comedy bullshit he's been doing for decades, this time playing a corporate whore who will be shitcanned if he doesn't cancel his Hawaiian family vacation and head off to Colorado to seal a business deal. And so he hauls his family across the country in an RV, and everything goes wrong along the waywith the lone highlight of the film being when Robin is buried in a pile of shit after the RV's septic tank explodes. Serves him right.
