Saw this a few nights ago and wasn't impressed. It's sad to see a master like Argento amount to this. The whole thing felt like a tv movie. The colour pallet was so bland it was surprising to even thing Argento was involved. No bright and colourful lighting in this one. Also, no inventive camera angles. It was all so standard I could only make it an hour in before deciding to skim through the rest.
I will say that the effects weren't atrocious. Sure they were bad and didn't fit the film but that was because they looked cartoony. They were well rendered and looked alright in a Who Framed Rodger Rabbit kind of way. The effect that bugged me were the flies; so unnecessary.
