Sweet Home is a series that made me invested from start to finish. Something that was 50+-minutes episodes started to feel like 20-minutes episodes, and all I wanted to do was to go to the next one. There wasn't a moment where I sat back and wished that I did something else.
I would say that the story is more action-related than horror related, even though there were some really great horror aspect designs in the series.
The story has good character developments and a good storyline, with great actors. Especially Go Min Si who always make me want to throw her characters out the window as she plays such bitchy characters in what I've seen her in so far. Kudos to them all.

I'm usually a person that thinks that VFX can sometimes mess up everything when it comes to a series, which often makes me stop watching. So naturally in the first episode I was skeptical, but as I progressed through the series the VFX grew on me, and I'm happy they chose to do what they did.

Music wise: Please, stop using the same song over and over. Would be nice to hear something else than Imagine Dragons "Warrior" once in a while. Probably one of the few complaints I have.

Other than that it was a great watch, would probably re-watch in the future.
