What with the horrid likes of Date Movie/Epic Movie/Meet The Spartans floating around, like floaters in the porcelain bowl of life, it's a genuine pleasure to come across a proper spoof - rather than a 'Vague Genre Movie' (check out Maddox's site for a witty-as-usual piss-take of such piss poor efforts as Meet The Spartans).
Walk Hard pretty much lampoons one movie only - Walk The Line (the excellent Johnny Cash biopic) - and then goes off on it's own, as if Walk Hard wasn't based on anything at all. It takes one idea, then runs with it on its own. It doesn't take clips from YouTube and insert them hap-hazardly into 300 vs Transformers mash-up 'jokes'.
It truly is a shame that Spartans can take the number one slot, it really is, because it means there's enough people stupid enough to pay to see such garbage.
Anyway, back to a quality spoof in the shape of Dewey Cox ... while perhaps a tad overlong (the 1970's period begins to flag a little), there's a genuine sense of humour amidst the quite faithful spin on the Cash biopic. It's silly throughout, but in a smart way - rather than stupid in a really dumb, moronic, un-original way like Date/Epic/Meet.
There is a danger with all this though, by which I mean the flood of Apatow-related flicks coming out. While he and his various teams are all highly talented, very funny people producing genuinely hilarious movies with real heart & even soul behind them, you don't want to overdose the audience. You never want to hear "ANOTHER movie with Seth Rogen?!" - mind you, such a thing is far from a depressing vision, but even too much of a good thing too fast can be bad.
Hopefully they've already realised this issue, it would be a shame for audiences to tire of the Apatow/Rogen/et al freight train, especially prior to the sure-to-be-excellent Zack & Miri Make A Porno.
Apatow & Co fans, rest assured, Walk Hard will be right up your street. As for the Date/Epic/Meet morons, this is how you're supposed to make a spoof movie - if you're still not convinced how to do it, watch Airplane! as well.
