"Walk Hard: The Dewey Cox Story" is fucking bloody hilarious. Where to start: The succesful use of every rock music cliche ever. The way it earns that R rating. John C. Reilly's genius. Jenna Fisher's positive attributes. The succesful merging of the Apatow and Saturday Night Live universes. Jack Black as Paul and that Apple dude in those Apple commercials as George (I have no idea who John was and I suspect the pie fucker from American Pie was Ringo- appropriate). The music. The lyrics that deserve your attention. The loving skewering of the last 50 years of American popular music. And just when it gets old in the tooth it wraps itself up nicely. It's all there folks.
