Arguably, there’s something poignant in the sight (you couldn’t say “spectacle”) of Vin Diesel delivering the American fantasy of muscle-car omnipotence just as Detroit is being stretchered into the ICU. Inarguably, this fourth entry in the franchise that began with The Fast and the Furious (2001) is a bloated, incoherent, 147-minute snooze. For what it’s worth: hot-rod outlaw Diesel grudgingly teams up with lawman Paul Walker to take down a Mexican drug lord. Director Justin Lin (once an indie darling with Better Luck Tomorrow) opens with a half-decent action sequence, but it gives way to murky nonsense combining CGI abuse with the worst sort of Bourne plagiarism. Stay home and huff gas instead.
