If you survived the 70s, you know what a good job this movie does of evoking that trashy, dopey, low-class decade. The ensemble cast is excellent -- it was Burt's best movie since Deliverance, Wahlberg is perfectly cast as the clueless stud, and most everyone else does great as well. Like the porn it satirizes, the sex is sometimes sexy (Wahlberg and Julianne Moore's scene), but more often sad. With a bouncy pace, fluid camerawork, hideously accurate costumes and an excellent 70s soundtrack, it boogies along very zippily for the first 90 minutes or so. Then it's the 80s, the party's over, and things turn much grimmer and slower for the last hour. Pretty much the whole ensemble has to pay the piper, often in violent ways. I've always felt that last hour was a bit heavy-handed and repetitious, and that at 2.5 hours the movie could've used, say, a 30-minute trim. Still, it's very good.
