Which, to be fair, is also what the tv series was (or in the car at night trying to look serious). Except that Ferral, with all the will in the world, could never be anything approaching what Don Johnson was in the mid-'80s.
But for all the shallow ridiculousness, I wasn't kidding when I said I really enjoyed it. I've watched it 3 or 4 times already. It's pretty vintage Mann, for all the good and the bad that entails. This is probably a minority opinion, but for me, it's infinitely more rewatchable than Heat, for example. I almost feel like watching it again right now.
