"Howling V: The Rebirth" 1989, directed by Neal Sundstrom, starring Phil Davis, Victoria Catlin and Ben Cole. This particular sequal saved the Howling series because it was a very different type of Howling. It had a serious tone. It was darker and eerie, set in a Medieval castle and a werewolf lurked within the passages. A group of people were invited there to the castle in Budapest, although something seemed off. The castle projects a sinister vibe. 500 years earlier was a bleak "Red Wedding" style history of the castle. I thought this was a very creepy film with real horror.
The most frightful thing about it was getting chased.
I mark this film a 7/10.
