I've always intended on seeing it again, because IMO it's the best rendition of #Mary_Shelley's 1818 classic I've had the pleasure of seeing. The character development alone leaves all of the other adaptations in the dust, along with a large dose of empathy for those involved.
As a companion, I recommend the #Project_Gutenberg version of Shelley's gothic novel in prose; I personally prefer .epub but both the film and the original work by Shelley are more closely aligned than any of those old #Boris_Karloff horror genre flicks that, in turn, influenced the creation of the beloved television character, #Herman_Munster (an old film professor of mine would freak out in the lecture hall anytime someone raised their hand and referred to any motion picture as a flick, lolz).
In a major departure from Shelley's original, Mason's portrayal of the character Dr. Polidori isn't actually in the book - the real John Polidori was a friend of Shelley's who himself arguably launched the #vampire_genre with his 1819 short story, "The Vampyre", once erroneously attributed to Lord Byron. Discussions between Polidori and Mary's husband Percy Shelley are largely credited with the genesis of the Frankenstein story.
If you happen to watch, Frankenstein - The True Story, do please comment back to let me know what you thought :)
My favorite line from the movie, that I've often regularly recited over the years, is:
Beautiful Victor... Beautiful.
On rare occasion, I'm sometimes asked what I'm referencing when I say that, like, after a successful compile, or fresh OS installation :p
