I thought it was a hoot! The cast was great including Pedro Pascal (best known for his portrayal of Oberin Martell on GoT) in a surprisingly funny and witty role. Damon and Tian Jing had very good onscreen chemistry/rapport (note that she's not a love interest in the conventional sense). I thought the effects were good and the action scenes well done. I realize the reviews weren't very positive and the film was lambasted by the SJW's well before a single frame of film was released, so it started out in the hole. But I don't think it was the "white savior" thing at all, and it annoys me that the clicktivists start their crusades without a clue as to what a film is actually about, just indignant about casting decisions they don't understand.
It won't win any awards but the acting is strong, the effects are good and I found it to be pretty entertaining. YMMV.
