Eh, I like an interesting spin on a classic. I’ve seen/heard the Frankenstein plot and small variations on it many times, taking a different direction is a good way to keep in a general universe but develop something new. If you’re not going to come up with new interesting content, at least don’t rehash the exact story I’ve heard many times. But that’s just my preference—I really enjoyed it and have become a fan of Guillermo del Toro works recently (due to exposure on Netflix). I’m not huge critic really so I won’t speak to artistic merit but I can at least say I really enjoyed it.
