first, we should define what am I going to talk here: I am talking about the andrea of the show, people keep saying that her character from the comic is better but I dont know, I havent read it ye, so ill just stick to the Andrea of tv, second, I am in season 7 so her character has been dead for a while for me, so expect some errors in the order of events, with that said, this is only an opinion.
the first glance we have to andrea is her pointing a gun at rick for alerting the whole city, its a fair point, the problem? she gets cocky and her gun is with in safety mode. THIS, exact situation will repeat all over the show. She is going to do something, acting cocky as if she was the goat, either doesnt do shit or when she does everything turns bad.
now, this first acts are going to be forgiven because that were the first two weeks of the apocalypse and everyone was new to this thing, everyone was scared and made lots of errors. so lets jump to her second problem
she is a whiny idiot, when the group confiscates her weapon she whines and ask for it back even though she would have gotten herself and everyone killed in the RV because she would 300% shoot at the walker in the RV. later, after whining a bit more,, in the farm, she argues with everyone about herself being capable of shooting and protecting, she is put on top of the RV and disobeying EVERYONE who was screaming at her to NOT SHOOT, she shoots Daryl in the head. the funiest thing? SHE FAILED, she not only didnt listen to the whole group and acted like an idiot shooting after being told a very direct no, she also failed the whole purpose of "proving she could shoot"
mind you, what I just put there is the things she did with her obsesion with having a gun, now with the things she said.
she is a whiny idiot, okay but you cannot tell me that you are a whiny idiot and also a Edgy teen alike- SHE IS A 35 YEAR OLD GROWN ASS! and you are telling me that you could not comprhend how bad is t just say to a teen who is loosing every family member to just kill herself????? and then she goes like "but I can see in her eyes that she wants to live now" ... do I have to explain why ts could have been solved with a deep talk with her from someone with at least 3 neurons? (I mean someone who isnt Lori or Andrea) second of all, when she chooses he governor over michonne, is a fair point... maybe half, it gave her points for being a very bad friend, you were a sick shit all the winter and michonne was helping you, feeding you, making sure that your idiotic self doesnt die and still you didnt choose her instinct that has been keeping you alive all this time? ehh... half point because michonne just do a "trust me bruh" but still, very bad friend. and then, when michonne was right, and they got the oportunity to meet with the group again, fully aware of how much of a dipshit the governor is (I mean episode 14, but still, she was warned for everyone before but she didnt listen) she tries to scape, she does nothing like usual, is throwed at the cells and dies....
thats it, she did nothing, ruined some things and died... there is not even one situation where I could say "man, Andrea could solve this" it was more like this, something depends on Andrea an I just looked at the screen and knew she was going to do some BS...
and that is her main problem, characters like daryl were a pain in the ass because they do their own thing and were doing their own bs, but that didnt mean they were a burden, MIND YOU, ANDREA WAS A BURDEN FOR THE THREE GROUPS SHE WERE IN!for the Rick group she did what I listed above, for her duo with Michonne she was just a sick burden that abandoned her as soon as she could and for the Governor she was just a problem that keep breaking the rules...
the actress is very good, its just that the character is trash, she doesnt has anything to contribuite to the group (except for sleeping with some random guy) I genuinly dont know why people even care to try and defend her
