It’s hard to overestimate the impact of Universal’s classic monster movies. They brought the themes and techniques of German Expressionism straight to Hometown U.S.A. and forever defined our notion of horror movies in the process. Every Halloween decoration ever made owes them some debt. Every onscreen boogeyman and misunderstood outcast can trace their roots back to them. They’ve become so ingrained in pop culture that we scarcely acknowledge their existence anymore… save during moments like this one, when they make the leap onto a new medium. As part of their 100th anniversary celebration, Universal has packaged eight of them into an “Essentials” Blu-ray collection, a handsome set that nonetheless stumbles into a number of expected pitfalls. Hit the jump for my full review.
