Query: Hitchcock's masterpiece...

The Birds is Hitchcock's masterpiece. It is my official selection for the best Hitchcock movie EVER...It is so much more than just a horror movie - especillay when you start asking yourself why the birds attack. Could the bird attacks be fueled by female sexual hysteria and competition for the only virile male (Rod Taylor) in the film? Or could it be just mankind's payback for abusing the fowl of the animal kingdom? This film is loaded with haunting images and symbolism which deserves multiple viewings and discussion among serious film buffs. Not only is the film worth 5 stars but there is an impressive flock of DVD extras. The film itself is a beautiful widescreen presentation with very nice sound; the extras should thrill Hitchophiles with a "making of documentary", vintage newsreels of the film's theatrical release, a very witty original trailer, deleted scenes, and Tippi Hedren's original screen test. YES!
