The most important advice from the various reviews I read about Barbarian, Zach Cregger’s (Miss March) first stab (pun intended) in the horror genre, was to know as little about the film as possible before watching it. As many of the reviewers I respect mention this in the early parts of their reviews, I will do the same. If you need some assurances before making a decision, watch the first part of the trailer. If you have enough data to decide, cut off the trailer.
