Of the 3 versions, I perfer the extended cut. But the only thing I don’t like about it is the use of stock music during the apartment raids and re-fueling sequences. It makes the movie look more dated than it really is.
One other nitpick, the actors commentary should’ve been on the extended cut. There were many occasions when the actors were gleefully waiting to comment on some famous scenes…Only to find out that Argento deleted them.
