Conan The Barbarian(1982) and The Vikings(1958) are much better entertainment.
If you want to waste two and half hours watching pointless and ludicrous filth with a sub-political undertone, discrimination and occult perversion, then go ahead, be my guest.
But Kirk Douglas produced a much better film that the late, legendary Richard Fleischer directed. Now that film was very worth it. If you have not seen it, please do so as it is a very good film and keeps true to events of that era.
The next movie is Conan and I will not delve into it. It is the stuff of cult action-adventure films. The Northman is a bland Hamlet type revenge film with mediocre and bland acting. There is nothing new here if you are a veteran movie buff. If you do decide to watch this one, be sure you are able to sit more than two hours of watching banal characters on screen strut their stuff.
