Jackass Presents: Bad Grandpa

"The novelty of a dude pissing unwitting people off with overt expletives disguised as an old man wore pretty thin in the Jackass TV series – 90 minutes of that would have been agonising. Fortunately, Jackass Presents: Bad Grandpa opts for more effective slapstick humour and antisocial absurdity that most of the unwitting participants have a good laugh over once the ruse is revealed (as seen in the credits)."

"Even at its low ebb, the movie effuses an infectious, mischief-making joy."

"Most of the gags fall flatter than a Knoxville belly-flop."

"There are a handful of brilliant set pieces, including a scorched-earth attack on child beauty pageants. But this exercise in wink-nudge bad taste simply leaves a bad taste in your mouth."

"It's hard to score big laughs with hidden-camera material these days because there has been so much of it... but Knoxville and his young sidekick still land a few jaw-droppers."

"Sacha Baron Cohen's "Borat" set the bar very high for this type of narrative-driven prankery, and in comparison, Bad Grandpa comes across as disjointed and aimless."

"Though the plot is predictable, individual scenes (and individual targets) are anything but. In the film’s best moments, it’s more than funny; it’s exciting, and almost as daring as its indomitable lead actor."

"Focuses the general air of collegial numbskullery into a buddy-pic bond between Knoxville and the very well-cast Jackson Nicoll."

"True to the Jackass formula, some gags come off better than others, but there's some doozies in its midst."
