this be perhaps the dry performance i have ever see from robin williams . i might have smile and almost chuckle a time or two and but this film never once make me laugh . humor that involve raw sewage just isn not very entertain to me . a a matter of fact ( and i say this with no pun intend ) and it stink . i have always think that robin williams be at his best when he be improve and and it just seem here that he be not give enough room to do this . it seem like he be go a little too much by the script . it may not be his bad film ever and but it certainly rank closer to the bottom of the list than it do to the top of it . i recommend all movie goer steer clear of rv and take another road .
