Just watching my Blu-Ray of 'Tenebrae' again. Such a superb horror movie. And what a soundtrack!
It's one of Dario's best thrillers indeed, one of his most accomplished movies! It's stylish, creepy, cleverly plotted, tightly paced and disturbing.
The POV shots are superb and unsettling because they make us, the viewers of the movie, "being/becoming" the killer, spying/watching at his (often gorgeous) victims in their cold modern houses , making us "feel" the killer's thrills and insanity when chasing his victims and then killing them...creepy daring stuff. The dog/chase scene is for example THE big set-piece , the most scary bit of the movie.
I also don't forget the very effective soundtrack, Luciano Tovoli's superb "shiny" white cold camerawork and the cool B movie casting.
I also like the deep clever irony of the plot, Argento mocking, making fun of the people/critics who for a long time accused him of being a sadist, pervert, misogynist...here in "Tenebre" Argento makes of the "hero" an artist like him, his twin brother, being accused of all these not politically correct things, all these crimes...SPOILER!!!!! who at the end turns out to be the killer!!!

...there's a kind of nihilistic tone in this movie, very powerful...among others the crazy finale ending in total despair, blood bath, screams and rain!

For the record, Dario will be back in France this month with his daughter Fiore (seen in "Demons" and the opening scene of "Phenomena"), to sign copies of his great autobiography book released last year, and also to introduce screenings of "The bird with the crystal plumage", "Deep red" and..."Tenebre"!
