Although it's overshadowed by its predecessors, it is the one that introduces Igor and inspector Krogh - the latter turns out to be the most interesting character while the monster takes the backseat this time around. It capitalizes on a legacy of late Victor, pardon me, Heinrich Frankenstein. His bloodline turns out to be a curse for fellow citizens and this is the movie that brought paranoia of the townsfolk.
The teaming of Rathbone, Karloff and Lugosi making it the most star filled of the Universal Frankenstein movies. Lugosi even deliver one of his most nuanced and strongest portrayals. It is the unsung final entry in the Karloff trilogy and a better ending than it gets credit for. The biggest problem here is that the monster is now more brainless and controlled by others.
Under-rated third film in the series continues the story many years later with the son of the mad doctor returning and being coaxed into continuing his father's work. Hard to watch without invoking the spirit of the later parody 'Young Frankenstein'. Lugosi gives a performance of note here almost making up for the ham of Rathbone's turn. The last Karloff appearance in the series.
The weakest but most fun of the first Frankensteins. Maybe even the best set design. Mel Brooks basically just rebooted the script, heightened it only a tiny bit, and added some songs to make his masterpiece Young Frankenstein. For that alone we owe this movie great praise.
Lee doesn't have Whale's facility for fluid camera movement but SON OF is a very good & overlooked chapter in the FRANKENSTEIN saga. Rathbone is especially excellent, but the film belongs to Lugosi, whose physicality--stoic/creepy, menacing/impish--is a lost art. Karloff, unfortunately, doesn't have much to do. Incredible set & production design. Welcome gallows humor but overly long.
The film that restarted the Universal horrors for the 40's. Undeniably classic and better than Young Frankenstein would have you think. This is just so well made that you can't tear yourself away. Unfortunately none of the later sequels really kept up the same quality.
