I finally picked up the BD as it was starting to disappear and I didn't want a large ugly hardbox. PQ-wise, it was actually a little better than I expected. The noise is there but it's definitely around the City of the Living Dead level if not slightly better and actually looks pretty good in some parts I think. The opening few mins are pretty harsh but it seems to improve overall. Certainly a big step up from the Severin DVD.
Now, what the fuck is up with the English track?

A complete balls-up of a mix with all manner of flanging and phasing. It's only just about bearable. I thought maybe they'd tried to squeeze down a 2.0 mono track into 1.0 but I checked the included DVD which supposedly is 2.0 and it's the same. God knows but the Severin audio and the German track are fine. What ended up a surprise in the PQ ended up being totally let down by the AQ!
