Sure, it doesn't have the nice fancy packaging, the postcards, poster, loads of special features etc (there still are good features, 3 interviews, one with Argento, 2 of which in HD, an intro by Argento, and the trailer) but why exactly do we buy a blu ray version of a film we really like?
That's right, the TRANSFER.
I must admit, I was surprised at how naturalistic the transfer was on this release, no DNR, or fake grain, it feels like Blue Underground (who I now prefer to stick to over Arrow, who seem to be concerned with practically everything but the transfer itself these days) have done a great job, they don't tamper with the transfers like Arrow do (The Beyond, anyone?), and the grain that is present, is natural, the colours are vibrant, it's nice and sharp, so if your a fan of Argento and this film in particular and want to see a PROPER 1080p upscale taken from the ORIGINAL print, then you need to buy this region free one.
I'm not hating on Arrow, they've done some fine releases, such as the Battle Royale boxset (perhaps the best blu ray I own own), and the transfer on Phenomena was excellent, Deep Red was 'ok', (but the blue underground transfer is leaps ahead), Dawn of the Dead was a terrific release (with a top notch transfer, 2 other discs of different cuts, including an Argento cut) and a heap load of features, but they seem to be getting somewhat 'inconsistent.'
It's also great that Amazon, at the time of purchase, were selling this product themselves rather than a second or third party importing it overseas that takes years to arrive (it arrived within a couple of days). Grab it when you can. I already own the Arrow version (which I'll just keep as a collectors novelty) but whenever I want to see this Argento classic, I'll always stick this one on instead.
