I will say that I did have quite high expectations for this movie and it did not end up being as good as I thought it would be, however, I really liked the acting and the music, both were really good. The way the movie was filmed(the lightning, angles, everything) was also really good.

The ending was really unsatisfying and the explanation for everything(why everything happened and the motives for it) was really weak. There are lots of unanswered questions or answers that quite frankly really don't make much sense.
The movie as a whole has a really uneasy vibe/feeling to it, which adds a lot to it even if nothing particularly odd/scary/weird is happening at the moment.


[spoiler]There was a particular scene that made me flinch so bad because it looked hella painful (the scene with the tooth drilling, ouch).[/spoiler]
[spoiler]So the secret to a longer life or maybe eternal life is..... eel sweat...eel derived sweat .....what even.
Also the fact that the baron would do all that shit just for a _pure_ bloodline just seems kind of weak and far fetched to me.
I guess there is symbolism for workaholism and making work your life. People want to cure something that isn't there and just end up actually getting sick instead....I don't really know what I'm supposed to feel about this movie or what the intentions are or what deeper meaning it actually has.[/spoiler]

It wasn't a bad movie, and it certainly wasn't a masterpiece but it was unique, so at least that's something.
I don't want to make it seem like it was a bad movie, because it wasn't. It did keep my attention throughout the entire movie and I never once felt bored.
I also didn't have a problem with the length of the movie(it being almost 2 and a half hours long). I never caught myself thinking about when the movie was gonna end and I was never bored of it either which I'm guessing has a lot to do with me really wanting to know the answers to all the questions I had and I think that might be the biggest reason as to why I got disappointed.
I was expecting this big reveal at the end and it just never happened, a lot is left to interpretation and it just didn't feel complete.

Would I recommend it? Maybe , if you're someone that's sick of seeing the same old things over and over and actually want to see something somewhat original then yes, I would recommend it.
If you just ask for a movie recommendation then this movie would not be at the top of my list and there are lots of other great movies I'd recommend instead.
My point is, it's not a must-see but it is worth seeing.
