I come at this from a biased standpoint, I'll admit: I loved the Dr Jekyll and Mr Hyde movie that this is based on and am always excited about well done spoofs. This is a very well done one: Stan Laurel's John Barrymore is spot-on, and the hijinks gets up to genuinely made me laugh so much that my face ached (thank god it was only a two reeler!). It's probably funnier if you're familiar with the original, but it has enough merits aside from that to make it enjoyable for most silent comedy fans.
