Decent watch at best, probably won't watch again, but can recommend for those on a late-eighties nostalgia kick.
Sometimes it is good to get in "The Way Back Machine" and see some of the movies that made people famous, and I liked Dan Aykroyd and John Candy.
The duplicitous plot and character choices just didn't sit great with me. Having recently seen "Brother Nature", it is interesting to see a movie that could have inspired it. I think it would have been a lot better with John Candy as an overwhelmingly positive buzzkill and Aykroyd playing a family man. But Candy is sort of the family man of the late 1980s, and Aykroyd is the quintessential New York scumbag, and they do it well.
I'd ultimately say it is worth the watch, but there are probably a dozen "back to nature" movies I could recommend in front of this one.
