To get Goodyear to a more habitable spot, since a bare hand burns up like a vampire in the 140-degree sunlight without a protective suit, the three set off in a jacked-up RV reminiscent of the one Jan-Michael Vincent tooled around in in “Damnation Alley” (1977).
Dewey is merely on-hand to help Finch forage for supplies, since the warm, comforting smile of America’s Dad suggests there’s nothing truly terrifying lurking in the dark; no Omega Man light-averse mutants or giant scorpions from 1977’s Damnation Alley that’ll require Hanks to throw haymakers, pick up a flamethrower or fire the pistol he flashes in one brief shot, suggesting that even Checkov’s Gun didn’t survive the apocalypse.
Essentially a bizarre cross between the two notable 70s-era post-apocalyptic sagas "A Boy and His Dog" and "Damnation Alley"--minus the various weird and grisly elements that cropped up in those projects---"Finch" wants to come across as both a profoundly moving testament to the enduring power of humanity under the most trying of circumstances and as a tour-de-force performance for Hanks in a film that, save for the dog and the CGI robot, is basically a solo gig throughout.
