I haven't seen it in a while (two or three years), but after the last viewing I loved it and thought that it was the best of the series. I liked the claustrophobic mood, the (relative) low-budget feeling it had - kind of hand-made - the 80s setting, and the horror elements. 
The first couple of times when I saw it as a kid and a teenager I didn't like the film, as I thought it was too dark and slow, but the many rewatches were rewarding in the end.
But I'd have to see it again to say anything definite 
I just hope I won't be disappointed.

Didn't know a new DVD was out. What's the missing/deleted footage?
