With Frankenstein, we ask the question: are we creating a world for the next generation, or just in our own image? We follow Mary to see the story of reckless pursuit and its consequences.
The whole space is divided into two worlds: Dark grey and flesh red. Mary is from a higher position, and she observes the story. There is a bridge from Mary's world to the story world. We can see Victor as a reflection of Mary, and see Creature as a reflection of Victor.
Act I is from Victor's perspective: logical and rational.
Act II is from Creature's perspective: distorted and chaotic.
