It was an obscure movie until Criterion Collection, almost arbitrarily, decided to release this on DVD. It was good in a late-night UHF kind of way although it reminded me, in terms of philosophy, of The Brown Bunny
sans fellatio. But the laid-back, "let's have a race and wax philosophical" thing works for a 1970/71 movie... a tour of roadside America that at least mirrors the fiction (Updike, Nabokov) that all the kids are raving about.
Two-Lane Blacktop? My response: Kings of the Road
. If you want to see two people drive (for three hours, no less) and wax poetic you can do no better.
