To be fair, I have up after maybe 30 minutes. I’m usually a sucker for historical stories, but this was quite tedious.
I ended up looking the fellow up (because I couldn’t imagine someone who had done what he had being as poor a conversationalist as he was being portrayed) and ended up reading a couple of articles about him and decided the movie was telling, badly, what it should have been showing.
The acting was fine and the actor had or was given a good resemblance to the man (so far as we have images).
