I have to agree with jan_ulalume's review in that this may be avant-guard to those who have never seen such imagery, but to those who have (in essence) grown up on this stuff, it is more akin to a "giallo's best hits".
With the "camera looking through the clear lightbulb shot" from SUSPIRIA (along with the colored lights directed onto people and key subject areas), Fulci's preoccupation with eyes and nose bridges, even encompassing Bava and countless other Italian filmographers filmic visual ques (WHO SAW HER DIE's funeral veil POV), like the former reviewer states it becomes over-saturation of style to the point of becoming ridiculous.
I will say that the first segment with the little girl is the best, simply due to the fact that there seems to be more of a coherent story that one can follow compared to the other two segments, which focus primarily on visuals alluding to some set of visual metaphors (even Zalman King wouldn't go this far), not to mention that the last segment's "twist" is (regardless of how predictable it may be to those familiar with these things) isn't built up very well at all.
Regardless, I would still suggest it (at least the blu-ray, as the clarity may help the viewing experience a bit) at least just to take it in. Maybe with some editing and some more giallo music (as the second and third acts are nearly music-less, which hurts those sections quite a bit for me) the movie could come across better...
