Yes it was absolutely unwatchable. I destroyed my tape in an ape-like rage after watching it (though I did remove its scalp and transplant its heart first).
What made it even more ridiculous is that the video had been pre-cut by Satanica before the BBFC had chance to see the uncut print. Even in the early post-Ferman 1999 it wouldn't have received that many cuts anyway (possibly only the bedroom assault). They literally removed every shot of gore and nudity in the film.
The Vipco
Eaten Alive video/DVD is exactly the same. The cuts look as if they've been done by a cannibal.
