Ive been blocked from finishing the game because of a bug untill today and reading again and again how bad ending is I expected something really bad. With such low expectations Id say its ok. Not great, neither as bad as some say. The only thing I wish we could see some hint for
Karlach being up to some way to have a better future and returning to us, or a short scene where she visits us.
I kinda like bitter sweet endings the are more emotional and tend to leave a stronge and lasting impression, but she is just too nice to not have something more.
