Damien Riley’s review published on Letterboxd :
Vincent Price is good at spooky. In this, I learned he is good at evil too! Picking out a husband and a father from a crowd and forcing them to fight to the death in front of the daughter/wife ... that's one example.
I found this movie highly engaging and certainly it kept my attention. Unfortunately though it had the look of a Shakespearean play and not a horror movie. I would recommend this as an adventure/drama but as a horror it doesn't stand up. That is, in today's arena.
The story is great and as I said, Price takes no prisoners with his acting. If you're looking for an old school Machiavellian play with extremely good acting and characters, this might be for you. Otherwise, I'd pass.
