We didn't see the movie in the theatre, but I just went ahead and bought it at Wal Mart one day.
We watched it in the RV in September while we were out and just loved it. To us, it not only was classical Robin Williams, but totally slapstick/stupid/everything one might expect and predict, yet completely silly. To us it was just a feel-good film. I started referring our rig to "the big...." Being polite on the forum, I shan't repeat it. ;D
If you are a fan of that type of comedy, then you should enjoy it.
We have friends who own a 5th wheel and have been in Billings for a year. They will be back home shortly after New Year's. My immediate thought while watching it in September was to get together with them after they get home and watch it.
I'm one of those people who kind of goes through life laughing, so it struck a funny bone with me!
Enjoy!
