"Conan The Barbarian" is the best Schwarzenegger movie. It's better than T2, Predator, True Lies, etc. It's on another level and is a freaking epic movie!
And I've seen the opinion expressed a lot. Which means I can't really call it unpopular, though it also isn't a majority opinion either.
Where I would disagree is that his performance wasn't his best overall, despite it being his best movie. A good bit of the work involved came from direction, editing, and the rest of the cast as well. He didn't, however, do great delivering his lines.
Where I agree is that he didn't have a lot of lines. Most of what made the character shine was physical and facial. That's where he was great. He still is superb at that; he plays for the back rows, and it works.
For sure though, it's still his best movie overall
The Conan soundtrack is truly epic. Put it on while doing chores around the house, suddenly you are doing quests. Cooking? No you are making a feast to celebrate conquest!
