This Jackass: Complete Movie and TV Collection is just a re-packaging job done by the studio and as such, if you’re already own them you’re really only getting a more compact set. If you don’t have them, it is at a reasonable price and worthy of picking up.
Jackass Presents: Bad Grandpa was far better and a lot funnier than I had expected it to be especially considering the Jackass movies and show never was my cup of tea. However, most of the jokes land and there’s enough plot there to string the jokes and pranks together quite nicely.
