There was a time in my life that Conan was my all time fav movie period. When I got it for Christmas on RCA Video Disc
I watched it each day on Christmas break.
As far as Work Building, Musical Score, Set design, directing, and Cinematography goes this film is still top notch. To me Arnold's acting is fine in this film except for maybe his screaming in the Pit fighting.
The action is a bit dated and does not have the most realistic chorography but it feels like a piece of History in screen.
IMO its the best fantasy world building put on screen.. Because there is no CGI and all of in is filmed on camera I think its world building is even better then LOTR ?. But just by Gandalf's nose.
