Ride Along is a film so casual in its conception and execution, it should be titled Drive Thru. It stars Ice Cube as a lone-wolf Atlanta detective who disapproves of the guy his sister (Tika Sumpter) is living with. Enter Kevin Hart as a mouthy school security guard.
Cube dares Hart to spend a day on the job with him, and we're off to the paces. As cinematic precedents go, this action-comedy is most indebted to 48 Hours, except Ride Along doesn't have a suspenseful criminal enterprise to move the plot along.
Ride Along confirms a few things about Hart: (1) His scrappy short-guy persona is always amusing, and (2) His trailers are better than his films.
In this film, we learn that while he is a verbal acrobat, he's not much of a physical comedian, and Ride Along calls for a lot of pratfalls. Hart still has more tools than Cube, who is neither verbal nor physical; he's purely facial - and even there, it's subtle.
