From it's corrosive opening credit sequence accompanied by a haunting child-sung (and used as a sort of chorus throughout and even plays out AFTER the credits end - so stay tuned), to its biting criticism of Franco's regime in Spain (it's title, "Long Live Death" might be considered an ironic echo of Patrick Henry's famous "Give Me Liberty or Give me Death"). The film proper begins and ends with the military proclaiming they will be peace to the country even if they have to kill everybody! The film is told thru patented surrealist devices such as dreams, fantasies, extreme violence, naturist drama & erotic visions - sometimes all at the same time. Arrabal and Cinematographer Jean-Marc Ripert often use imaginative camera tricks including a then-novel use of tinted videotape.
With all this, I still can't wholeheartedly endorse the film. Much of it seems random or repetitive. It's clearly indebted to Luis Bunuel, SATRYRICON era Fellini & Jodorowsky (who of course, adapted Arabal's FANDO Y LIS - so the influence is mutual). Some of the visual metaphors are graphic in the extreme: Such as having the Mother (who is clearly symbolic of the morally corrupted country as a whole) actually cutting off the scrotum of a cow (and this isn't faked, in fact this is one film PETA members should not see).
A worthwhile curio to seek out. Particularly those partial to Bunuel and Jodorowsky.
