I wanted to love this. And I feel like I should have. But I didn't. I was interested in it enough to see it all the way through the end to find out the conclusion of the central mystery. Why was it just okay? I'm not sure. The performances were strong, and the period sets and costumes were amazing, but I would find my mind drifting throughout it, a lot. Too much. So I can only chalk it up to the script and the directing. The shots themselves in the movie were good. It looked beautiful.
But for whatever reason, I was never fully pulled in. And I think this was in large part because the crimes of the Limehouse Golem were all told as flashbacks essentially, there was no real suspense, except for one scene near the very end that I won't spoil. So yeah, ultimately I think the storytelling structure diminished the sense of suspense that should have been present in the story. The movie is also pretty violent/gory in those flashbacks, btw. That neither raised nor lowered my overall score of it, but it was violent enough that it's worth noting.
