A low-watt, low-wit comedy.
It almost seems like harder work somehow to get this many comedians together and then turn out a movie that is only so fitfully funny.
Its jokes won't appeal to anyone older than 8, but a parent who takes a child to this crass mess would be subject to prosecution.
After a lot of wandering around, we realize we've really just been walking in circles the whole time.
The humor in Nature Calls tends toward the dopey and obvious ...
The unmitigated disaster of the camping trip just stays disastrous, the story never really finding its way from adversity to heroic redemption.
There's nothing wrong with slack misanthropy, but as piss-takes go, Nature Calls offers a pretty thin stream.
As capably as the plot comes together, the big laughs hardly come.
A brazenly foul-mouthed but ultimately soft-hearted comedy of bad manners.
