I personally liked the ending

I am not going to review the series as a whole, as other reviews have already covered it well. What I will say is that I liked the ending. It gave me The Walking Dead ending vibes, in that they didn't miraculously cure monsterisation or cure/kill everybody who had already turned. The ending also gives us the possibility that we could see Sweet Home again in the future, after Song Kang's military service, should everybody wish to continue. We could see a mega final battle between the humans and neohumans vs. the monsters. That would be pretty cool.
