Eh, I'm sure I'll enjoy Machete when I eventually get to see it, but I'm already kind of tired of the whole Tarantino/Rodriguez grindhouse thing. It's all so tongue in cheek and knowingly ironic and whatever, it's become a bit of a director wankfest. I don't care so much about seeing a homage to exploitation films which undermines its source material by presenting those films as too ridiculous to be anything much more than fun. I'm sure that's not Rodriguez's true intention, but that's what happens if your "homage" is essentially parody.
Exploitation films, much like spaghetti westerns, have their own special flaws. There are lots of features which betray cheap production values, plenty of features which are comical to modern viewers. However, as any discerning viewer will tell you, if you look past those shortcomings you will find intelligent film-making with plenty of powerful and haunting scenes. Directors didn't en masse set out to make silly films, they set out to excite their viewers. I wish the likes of Tarantino and Rodriguez could restrain themselves and make movies in the spirit of the films they love, rather than collaging their favorite bits, warts and all.
Sounds like I need to check out Book of Eli, though.
