Hi, I just reviewed The Old Guard here on the Hive network, and I hadn't noticed your review until it Ecency showed it to me in the suggested "Read next" section beneath my own post.
I find it difficult to comment about the quality of acting; I suppose I just don't have an eye for it. This isn't really a big acting movie, I think, even though it's a big actor movie with Theron as the most important part of it. It's a character movie, and it would have been a bit better if the characters were portrayed with some more uniqueness, I think.
All the best to you, fellow reviewer.
