If you're a big fan of Jess Franco or Lina Romay then this is worth watching just to see newer work and compare it to the older stuff. If you've never seen any of their work, this isn't a good introduction.
The plot is convoluted and incoherent, as is much of Franco's work, but in this film he adds some cheap special effects, and as much of his trademark camera work as can be done with a video cam in a hotel room. It's basically a vampire tale, without the eroticism of their Lust for Dracula or the interesting things done with film in their earlier works. I say their work because I give Lina Romay at least as much credit as Franco, maybe more.
There is the almost obligatory scene of euro-skanks having pseudo-relations with each other, although it gets a little better at the end when Ms. Romay joins the action. She still manages to bring some fun into what would otherwise be a complete mess; without her I doubt anyone would allow Franco near a camera.
If you're a fan of the seventies euro-sleaze Franco specialized in, this isn't quite up to that level, although it tries. Watch it for a glimpse of what he's up to now, but don't expect a lot.
