Run Time: 82 minutes Probably the most beloved rockumentary spoof out there, This Is Spinal Tap cleverly points fun at the eccentric, high-ego rock bands of the '60s and '70s and its flat out hilarious. The dry, deadpan humor may not have you rolling on the floor, but its a prime example of satire at its finest while still respecting the rock and roll music culture. The improvisation is spot on and after a couple viewings youll memorize every bit of dialogue. Speaking of multiple viewings, you can easily accomplish just that because its so freaking short. Yeah, its only 82 minutes long so get to it.
