As a huge fan of Johnny Knoxville and the whole Jackass crew, I had high hopes for Bad Grandpa. Unfortunately, for me, this film added one fundamental element that all Jackass movies should be without…a plot. The movie follows old man Irving (Johnny Knoxville) and his grandson, Billy (Jackson Nicoll), as they travel across the country to reunite Billy with his estranged father while his mother serves out her time in prison. Basically, it is the perfect coming of age story…that is, until you actually meet old man Irving.
