Bobby LePire’s review published on Letterboxd:
While sporting some stronger atmosphere and charm than a lot of the early 1930's talkie horror flicks, this movie does feel a bit like a regression, especially when compared to the gothic impressionism of "The Golem", "The Cabinet Of Dr. Calagari", and (of course) "Nosferatu". Maybe studios wanted to focus on the dialogue given how new synced sound was, instead of the set design (or you know, one of the most visual aspects of a visual medium), but "Mystery Of The Wax Museum" is not, visually speaking, very sophisticated. The acting is alright, and the plot proved it could work. Thanks to the acting, and taut dialogue, this is not a failure, but it fails to live up to its full potential.
