This movie isn't one of Robin Williams best, as a matter of fact it's not that good. National Lampoons' Vaction is much better. This is just a remake of the Griswolds but in a over size RV in which seems to more exciting than the movie itself. It has a predicable ending and they won't make a part two, well let's hope not because it will be worse than this one. The movie has a few laughs but when all the laughs are in the trailer then the movie won't do that well. I noticed a few people in the theater were laughing throughout the whole movie, they must have been huge Robin Williams fans. All in all, is worth 6 buck to see it but it's not on my DVD purchase list when it come out in a month or two.
