I was surprised by how much I liked it.
Enola was adorable. I liked how she was a savant but at the same time, she was clearly sheltered and in over head in a number of situations. I was very impressed with MBB. Enola's growth reflected in her revised interpretation of "Alone" made me smile.
Enola and Lord Tewskbury were both so likable and had a wonderful rapport. I did not call the ultimate villain in the story, so was literally shocked when the mastermind was revealed.
I also really liked Henry Cavill as Sherlock. The slow rapport he was forming with Enola was wonderful to watch.
All in all, I hope we get a sequel.
