It's always a crap shoot whenever a Hollywood film tries to bring martial arts into mainstream North America. Jackie Chan has for the most part bridged that gap successfully while integrating comedy. Unlike with his past comedic partners in crime from Owen Wilson and Chris Tucker. Johnny Knoxville fails miserably. It's not entirely his fault. It's the film itself. It seems to me Renny Harlin is trying to mash bits of Shanghai Noon with Rush Hour with a dab of Supercop. The film doesn't gel at all. The flow is all over the place and scenes are too implausible. Each scene, seems to be a gag. There's conversation/joke/story line implied then at the end of the scene, the punchline. Then it moves on. Action scenes are obvious Chan-born, which sometimes do not feel unique unlike his past Hollywood films. Feels too contrived, not original enough. I am a big fan of Jackie Chan - Johnny Knoxville is coming along trying to be taken seriously, but Renny can't seems to improve either actors and that shows in this outing. His last decent film, Long Kiss Goodnight should be used as reference to make better action movies.
