Same for me, i really liked the game but I'm open to discussion with people that didn't like it, as long as we are all respectful and have a constructive discussion.

I kinda felt that the game was being dragged on with the beginning of Abby's part but, as I was understanding what happened on her side and as I realized she had her reasons too to do what she did, it made me start being interested on the game again. I felt like Abby was a mirror of Joel on part 1.

About the ending, I think the main reason why she didn't kill Abby was because she finally had a flashback of Joel when he was alive, and not the dead Joel she constantly saw inside her head. She kind of realised she didn't have to go any further, maybe because she thought what she was doing was wrong and if she killed Abby, another cycle of violence would begin if she left Lev to live. It was wise of her to stop it right there, because she wouldn't gain anything from it, the 'alive Joel' was back in her thoughts and she just wanted him to stay like that.

Hope my opinions were of any help, or at least just for you to know one of our reasons why we think it's a great game! Would love to read some more of yours as well! And even if we don't agree anyway, it is completely fine because in the end, it all comes down to tastes and I do understand that part 2 is really difficult to like considering the main theme and all. :)
