Really not sure what all the fuss was about with Part 2 back when it was released, or how anyone could say that Part 2 is a travesty that ruined the franchise.
It was a mixed bag tbh - fans of the first, who felt invested into Joel and Ellie, didn't expect Naughty Dog to kill one of them off; and with a random character related to an NPC you offed in the first game. But how they added that arc was actually quite good.
The biggest issue for those fans, I think, were the half truths - I cannot recount them all as there was so much rubbish around at the time; but Naughty Dog were certainly guilty of some bait and switching tactics. The most prominent that I can think of, was a clip showing Joel telling Ellie he wasn't going to let her do it alone (or some such) - but when the game came out it was Jesse. That sort of thing was prett bad imo, as there's a decent chance that fans of the first, may have purchased the game thinking Joel would play more of a role than he ended up doing. But hey, subject to change and all that guff.
Sadly, there were also some right nutters put there too - who took it too far, and did the unusual thing of sending death treats, and hounding actors off of social media; the likeness of Abby left ******* because of it iirc.
For me personally, I was disappointed by the changes they made, but I still enjoyed 2 - though it didn't have the emotional connection of the first; I didn't care about Abby and her crew, and even Ellie grated on me a lot. I think the only time I felt something, was when the pregnant woman was scared and wide eyed during a cut scene. Other than that, the game just felt like a kill fest.
TLOU is still one of the greatest games I have ever played, and a huge part of that, was the story and the connection you had with it - but I just found the second one not to be on par with it; there's lots to like, but I just found it was a pretty gun fest compared to the first.
