Alternately cheery and dreary, Paul Thomas Anderson’s porn de force shines a blacklight on the adult film industry, and its awkward transition into the era of VHS and HIV.  Mark Wahlberg—sporting a prosthetic trouser hog—nails it as impressionable fuck boy Dirk Diggler.  Burt Reynolds is his match as the Colonel Parker who ushers his very own Elvis into the path of destruction.  The supporting cast is a roll call of Oscar nominees, and they’re all as good as you would imagine.  This movie is to pornography what Goodfellas was to gangsters.
