It's nearly a typical Giallo with red herrings abound in its mystery, an overly complicated plot, and being polished in technique but not in its depth. The Red Queen legend is a good creepy starting point to navigate its murders and the plot is often very convoluted with some loose ends coming up in its end twist. Yet, like any fair giallo, it's flamboyant enough that you should just take all the style in.
Honestly this flick has all conventional ingredients to make a good horror-mystery film with a sombre gothic atmosphere (old castle, family curse...). With a glamorous and twisted facet the timeless giallo signature is also here. Without being too ambitious it reaches its goal and can be compared with Sergio Martino or Mario bava’s best 70s euro-trash film production.
You can pretty much tell what's going to happen within the first 15 min or so. There is a sorta twist at the end but this being a Giallo, makes absolutely no sense whatsoever. Cinematography, locations, soundtrack, & acting are all top notch. making this one of the essential Gialli
The plot being not so interesting after all, I focused on the production design. The scenes take alternatively place in a gothic German castle and in a few apartments. Love Ugo Pagliai's bad taste for his flat's decoration. He almost deserves to be stabbed by the Red Queen. Recommended though.
It has everything you expect in a giallo, with it's ups and downs, the plot has no problem sacrificing some logic here and there in order to create dramatic tense sequences. I'm ok with that, a good giallo seduces your senses, it doesn't hammer them like any mindless slasher flick does. It has a fantastic score from Bruno Nicolai, a gothic atmosphere, dream sequences. Good fun giallo times.
