Frankenstein - Watch Order: Universal Films
The Universal Frankenstein series forms the most coherent storyline in the franchise, with each film building on the events and characters of its predecessors. Bride of Frankenstein continues immediately from the 1931 film's ending, while Son of Frankenstein introduces Ygor, who becomes a crucial recurring character linking the later entries.
The films maintain clear narrative progression through plot developments like Ygor's brain transplantation in The Ghost of Frankenstein and culminates in monster crossovers that unite storylines from across Universal's horror catalog. While there are occasional inconsistencies in character fates and abilities between films, the Universal series makes a genuine effort to maintain continuing storylines.
