Now that I'm older (well, still pretty young), I revisited this one. It's one of the few 30s horror movies that's genuinely disturbing, there was no limit to what Hyde could do. While he did goof around some of the time, he could turn deathly serious in an instance, and THAT was scary. The best part in the movie is when the door opens to reveal Hyde standing there. No words needed - his face says it all.

March gets a lot of praise for Hyde, and while it it is warranted, his portrayal of the good doctor shouldn't go unspoken. Previous Jekyll's were too... good. March's portrayal was not of a perfect man, but a normal, relatable man. His words about Muriel's father, and the face that he refused to turn himself in (as opposed to the tradition suicide) showed that even the good Jekyll had some bad qualities just below his surface.

In relation to the book, the mystery wasn't present, but the suspense was still retained. We get also get a drastically different view of the struggle being told from Jekyll, as opposed to Utterson
