Frankenstein originally came out the very same year as Dracula, both were massive hits, the film starts with an onscreen warning, no doubt back in 1931 this was considered very strong viewing material but this was also a great marketing gimmick that reviews of the time would have used to entice more viewers to come and watch the film, the movie actually made over $12m dollars at the box office, it also went on to spawn many sequels and inspire television shows such as The Munsters. Mel Brooks did a wonderful parody of the Frankenstein movies which was hilarious, go check out Young Frankenstein which is available on blu ray and be careful you don't laugh yourself to death.

The film ran into censorship issues on it's original release in many countries, cuts were made in the UK and in some states in North America, there was certainly censorship issues in the USA after the Hays production code began in 1934, the film ran into many problems with it's re-issue and Universal snipped footage from the original negative, luckily for us the cut scenes would be restored during the eighties and nineties and Frankenstein could once again be viewed as intended.
The transfer to blu ray is good, this is an upgrade for those of you who have only seen the film on television, VHS, Laserdisc or on DVD, i saw plenty of fine detail and black levels were nice and inky, compression is also handled well, the sound quality has been cleaned up a little although it's not as good as the aforementioned Dracula, i would imagine the audio elements they had to work with were not in great shape and they have done their best, it's a 2 channel DTS HD Master Audio mono mix, dialogue sounded clear to me and any issues you may hear with tinny sound, distortion or hiss are related to how the sound was captured back in 1931, so far i am happy with the Universal Monsters Boxset and the first two films out of that set.
