If you haven't played all the way through TLOU then your opinion is completely invalid, especially any criticism of its story.
The game was great, but it definitely has flaws. It's easy to see those flaws relatively early on, too.
That being said, there are a lot of people who don't know how to enjoy stuff without trying to feel like they have to pick it apart and validate why it's good enough and I do feel sorry for those people. I'm not accusing anyone of that here since they may have valid opinions, but I definitely see that with a lot of media. It's ok to like stuff even though it has lots of flaws.
