Sure, the trio is a lot of fun together and Jackie/Benny is good. But everyone ignores a crucial element, that beautiful machine that enables the films title. The van is a unifying force of family and love, without it they would be lost. This is shown when the family kicks Sammo's mission away which results in a photograph that frames only the family and the van, then one last cut to just the van. Credits roll on.
To be honest, most of this film's runtime is eaten up by leisurely paced slapstick, sight gags, and inane dialogue. However, the last twenty minutes are like dying and going to heaven for action fans. There's a reason Jackie Chan's bout with Benny "the Jet" is considered THE greatest onscreen fight of all time. If you've ever expressed any interest in the martial arts genre, "Wheels on Meals" qualifies as a must see.
