This is a great show, not so much for the writing ( which honestly kinda sucks) but for the characters. they are all pretty amazing.
Veronica- One of my favorite characters, she doesn't get as much screen time as she deserves.
Betty- She is an ok character don't hate on me for its but her whole "Dark Betty" thing kinda ruined her character for me.
Archie- Not so much an interesting character but would be better if he was dating Betty (No Hate)
Jughead-My another favorite, great character but would be better if wasn't with Betty. like I said please don't hate.
Bughead- boring, bland, we have had this ship for 4 seasons, we don't need more of it. I know it's a fan favorite but I really can't see the appeal. I mean if archie had realized his feelings earlier then they would have never even happened. I didn't mind them at first but now its just hard to watch.
Varchie- As with bughead they have been together sense season 1, sure there was that thing with reggie but that lasted like 4 episodes. They don't seem to have any intellectual relationship, they just makeout and... yeah.
Barchie- Sweet boy and girl nextdoor trope, couldn't ask for more. Betty is really mentally breaking down in my opinion and archie could help her tremendously with that, Jughead just doesn't seem to realize. Not to mention they are quite aesthetically pleasing.
Jeronica- Not vughead people Jeronica, My opt, it would be interesting, angsty, new. We have seen the same boring ships for tooooo long we needed something new and fresh. They have that romeo and juliet trope, they arebot smart and love books, and old movies. Not to mention the height difference. You can't tell me that these to would make a cute couple, I mean we can all feel the sexual tension when they argue, don't ven try to deny it.
Beronica- I wouldn't mind it , better than bughead.
Jarchie- Ehhh I mean..... sure? its not horrible but I think there friendship is too strong.
That is my opinion on the core four ships and characters, I hope I helped someone. Have a wonderful day, you are amazing and beautiful.
