Because Amazon lists both as directors, I am suspicious
that this release contains only the re-worked film which Bava's son
'polished' after his father's death- for the worse according to almost
all Bava's fans as well as professional critics.
Both versions are on the US Anchor Bay release titled 'Kidnapped', so I'd
recommend that version, unless the Amazon information has lead
me astray. I watched Bava's original, and then the first half hour
or so of the son's 'improvements'. In the newer version
the score was weaker, some important character moments seemed to be
gone, etc. but the basic plot stayed the same.
In any case, I'd pick up that version instead. At least you can compare
the two for yourself. As for the film...
--vague possible mild spoilers ahead --
It's a film that is saved by the rare truly successful twist ending,
that changes everything you thought you saw. The acting is less than
great, and the film has a definite misogynistic tone (although everyone
in it is pretty awful on the humanity scale).
On the other hand, there's effectively high tension, as 3 murderous
robbers take two innocent people and a baby hostage. Especially
impressive that it never gets talky or visually dull, despite taking
place almost entirely inside a car.
But the over-acting and clunky dubbing (and writing) really hurt. Then
the end came and I was suddenly ready to forgive a lot.
