So literally the same vibe as the other two movies.:austin3 This feels less like partners and more like superstar Will Smith and his idiot sidekick.
Martin Lawrence has always been the sidekick to Will Smith in the franchise. Even in the first film which was before Independence Day when they may have been close to being the same level of star Martin was presented the less cool, less suave, less sophisticated, less physically gifted of the two. He was there to play the comic relief and somewhat of the moral centre that's his job in the franchise. There will no doubt be the classic partner type dynamic in the film but let's not act as if they were ever presented as equals from the get.
