Is this Jackie Chan at his best? Of course not, but if you like him or the particular style of movies, then you should be able to have fun with this. It's not really science to put a movie like this together, things just happen and the action sequences are decent enough put together (again don't look for excellence).
Even former Jackass and now Chan partner has a role that is fitting. He's no Owen Wilson of course or Chris Tucker for that matter. But he does his schtick and it ... sticks. The jokes may not have the impact some could have and many things are predictable, but that's the way it is. Don't overthink it (any of it), just sit back, relax and take it in
