The basic premise to this film is that 86-year-old Irving Zisman (Johnny Knoxville in heavy old age makeup) is taking his 8-year old grandson, Billy (Jackson Nicoll), from Nebraska to North Carolina so that he can live with his deadbeat father after his mom gets arrested for crack,
But the story is just a thin device to play inappropriate pranks on innocent bystanders for comedic amusement, in a similar vein to Sasha Baron Cohen's Borat or Bruno. A film like this is going to have its audience, and you really can't take this too seriously, and I don't think there is much I could say here to either make or break someone's decision to buy a ticket this weekend.
I think in reviewing a film like this, you can't compare it “quality cinema,” but instead judge it on a different set of critera. It's a movie that will appeal to your inner immature 13-year old, but does it succeed on that level? I would say it does, and I laughed harder here than I did in the aforementioned Borat or Bruno. Were all the funny parts in the trailer? No. I would say the best gags have not yet been revealed in the marketing, and I won't spoil them here either.
Ultimately, this is low brow and we all know it, but does it succeed at what it aims for? I'd say mostly yes. It's not perfect, but I can't lie. I laughed more here than I've laughed in quite awhile. Reporting, I'm Brad Carnall
