I agree that the writers are taking each element that made 1997 successful and amplifying it for 1994, but I don't think that makes this drama any less good. What I like about 1994 is that they developed each side character really well and they all feel real. Each of them has a story, and each of them gets little stories in different episodes. I think that people are getting frustrated with 1994 because they're focusing on the romantic parts. Yes, we all thought Bingrae was gay, and that he would end up with Hoya, and then he wasn'tm and that sucks for us (still think he's a repressed gay), but the truth is that they never said he WAS gay, unlike with Hoya, he was just confused, and I think that is way more refreshing than having "the gay character", because we already had that in 1997.
And as for who will Na Jung end up with (I think it's pretty obvious by now), both of them are really good, and I love them both, but it's not really about which one is better, it's about who she loves, and who she thinks fits better with her.
I get why people are so upset, and I was like that before, but now I'm just rolling with it and enjoying this drama for the friendship between all of them and their developments through life.
