I know this is an old movie but I wanted to give it a mention since it was a surprisingly fun movie to watch. There are no nudity, Evan isn't trying to make his wife's breasts larger, and I don't recall any bad languages. Rated PG but it could have been a G.
Not as slapstick or angry as Bruce Almighty. I did fear that I was going to get beaten over the head with "green" or with a save the animals/planet message but that didn't really happen.
Fun almost wholesome family movie that's quite predictable due to the abundance of foreshadowing. Not gutbusting comedy but amusing.
A highly recommended rental.
(I believe the PG is probably due to feces humor with the animals.)
