Bilge Ebiri, New York Magazine/Vulture: For all its flaws, it might just be the most heartwarming movie of the year. Read more
Kyle Smith, New York Post: This whole movie is pretty much a mental colon blow. Read more
Scott Foundas, Variety: "Jackass Presents: Bad Grandpa" shows there's still comic life in this decade-old franchise - provided, of course, the sight of a senior citizen getting his penis caught in a vending machine is the kind of thing that brings a smile to your face. Read more
Kyle Ryan, AV Club: Bad Grandpa mostly succeeds in its very modest goal. It's Borat without the satirical edge, with Knoxville and longtime Jackass director Jeff Tremaine taking the most outrageous parts of that film and escalating them dramatically. Read more
Peter Keough, Boston Globe: Though at times it grows predictable and more inane than outrageous, "Bad Grandpa" gets more than its share of cheap laughs. Read more
J. R. Jones, Chicago Reader: Onlookers occasionally glance into the camera, a pretty good sign that people are hip to these prankster movies now and just play along. Read more
Owen Gleiberman, Entertainment Weekly: You'll occasionally laugh out loud, but the heart of the movie is safe enough to chuckle at. Read more
Wesley Morris, Grantland: The wrongs pile up, and there's a clear object of satire. That feels new for the Jackass experience: a target that isn't a crotch. I'd like to see Irv try to strike again with braver gags. Read more
John DeFore, Hollywood Reporter: [The plot] focuses the general air of collegial numbskullery into a buddy-pic bond between Knoxville and the very well-cast Jackson Nicoll. Read more
Betsy Sharkey, Los Angeles Times: The film has a story complete with a beginning, middle and end. It has some acting and emotion. And most shocking of all - it has empathy. Read more
Amy Nicholson, L.A. Weekly: The joke is really on Knoxville, who, despite flinging himself through a glass wall and rigging up a fake poo-sprayer in his pants, gets fewer laughs than his boy sidekick Read more
Stephen Whitty, Newark Star-Ledger: Sometimes joy buzzers - and pratfalls, and funny costumes - are really all you need for a laugh or two. Or even a three-star comedy. Read more
Elizabeth Weitzman, New York Daily News: Knoxville and the perfectly cast Nicoll have great chemistry throughout. But longtime "Jackass" director Jeff Tremaine consistently cuts away too quickly, undermining each joke in order to rush on to the next. Read more
Neil Genzlinger, New York Times: It's hard to score big laughs with hidden-camera material these days because there has been so much of it since the "Jackass" TV show, but Mr. Knoxville and his young sidekick still land a few jaw-droppers. Read more
Peter Travers, Rolling Stone: It's not really a movie. It's Johnny Knoxville and his Jackass crew faking out real people into believing he's 86-year-old Irving Zisman, an old fart bag traveling cross-country. Read more
Peter Hartlaub, San Francisco Chronicle: Some of the pranks are masterfully executed; the beauty pageant and a disastrous funeral near the beginning stand out. But on the whole, "Bad Grandpa" can't locate a consistent groove. Read more
Dan Kois, Slate: What impressed me again and again is how unflappably polite Americans can be. Read more
Colin Covert, Minneapolis Star Tribune: My contender for funniest movie of the year. Read more
Dave McGinn, Globe and Mail: It's been 11 years since Jackass: The Movie, and three since Jackass 3D, although it feels a lot longer than that. Read more
Linda Barnard, Toronto Star: Like the lime-green bingo dabber contents Irving drinks down to the horror of his seatmates, it's an acquired taste. Read more
Alonso Duralde, TheWrap: When the three-act structure gets shoved to the side for fun and games, Bad Grandpa delivers some of the heartiest laughs I've had all year. Read more
Ashley Clark, Time Out: In Bad Grandpa, there's no shock value: the physical comedy is down to a minimum, replaced by a creaking humour almost as dated as Zisman himself. Read more
Sam Adams, Time Out: Apart from a handful of physical stunts and the penultimate biker-bar setup, Knoxville never puts himself at risk, and the imbalance of power curdles the imperative to laugh at the rubes. Read more
Scott Bowles, USA Today: Not only stands as the best installment (by bounds) of Johnny Knoxville's hidden-camera franchise; it's one of the sharpest comedies of the year. Read more
Michael O'Sullivan, Washington Post: Although we're allowed the perverse pleasure of watching Irving commit one inappropriate act after another, our sense of horror/delight dissipates after each one. Read more
