Detached, floating freaky eyes: that's what you see when you start watching Frankenstein. The title sequence is 100% freaky music and freaky floating eyes—in fact, it may be the creepiest scene in the entire film.
What do those freaky floating eyes have to do with Frankenstein? We talk about that a bit in Symbols: Freaky Floating Eyes, but besides their symbolic meaning, you could see the eyes (pun!) as showing you how the film's narrative works.
Because, in Frankenstein, you get to see everything…just like those freaky floating eyes.
There's no one narrative perspective in Frankenstein; you're not limited to a single person's viewpoint. Instead, the film takes a third person universal perspective—which means you can see everything you need to see, no matter where it is or who's there. Like Frankenstein, you can say:
"Oh, in the name of God! Now I know what it feels like to be God!"
(Except that would make you sound like a mad scientist, so don't do that.)
Instead, think about how the film shows you so much from so many different perspectives. You're with Fritz as he sneaks into the university to steal the brains; you're with Elizabeth and Victor as they muse about whether they should go to Henry's laboratory; you're with the monster when he meets poor little Maria; you're with Henry when he meets the poor, big monster.
You're everywhere, with everyone—nothing is hidden from you. As with Henry, the mystery of the universe unfolds before you.
But even you're helpless (even though you're all-seeing)—you still can't get that monster to say anything but "Argh," or prevent it from killing little girls.
