A lot of people have already probably said this but here goes:
1. My biggest problem with Sera is that she's tagging along to see if there's any truth to what the Chantry has told her, and if you are specifically chosen by the Maker/Andraste. That's fine, but then, she refuses to acknowledge anything that might challenge her beliefs at all. The whole conversation after the Temple of Mythal really cemented my dislike of the character. It isn't just that she's scared, it's that she absolutely refuses to even consider anything she just saw/experienced/heard about might be true. This is not a quality I admire in real life, and I find it rather abhorrent.
But that seems to be par for the course with Sera. If something doesn't conform to her ideas, she just closes her eyes and makes fart noises. She actively cuts herself off from any sort of growth.
Like "I want to see what's really real!" But only if it aligns with my pre-existing views.
Actual quote from Sera IG: "I hate learning lessons. Makes my stomach hurt."
Yes, growing as a person is hard and it's supposed to be hard. It isn't easy for anyone, and I do not find it a virtue to actively avoid it.
2. Her internalized racism feels extremely toxic and is unpleasant to be around. It also makes her views on helping "the little people" seem like BS when she doesn't give a **** about elves. Elves make up a bulk of the minorized population across Thedas. I was really hoping we'd have a party member who is for helping the City Elves but no. We get... Sera who is proud to distance herself from any and all elves. Also, I never got an adequate explanation as to why she so virulently hates elves?? Like we have to read about her growing up in the Denerim Alienage, I believe, rather than being shown or told about that. Like, I don't want to speak too much on this because I don't belong to in a marginalized ethnic group, but it's... not exactly endearing.
3. She gets SUPER annoyed when people dare to stop and ask questions. Like, excuse me for not accepting things at face value and maybe wanting to understand what the hell you're saying? It comes off as incredibly condescending, which is another personality feature that rubs me the wrong way. I know she's not educated, but that's no reason to not ask questions and assume you know everything? It's so maddening. One moment she's saying she's stupid but then in another moment she's acting all high and mighty because YOU the PC are asking questions and didn't instantly understand something. UGH.
4. She is full of all sorts of hypocrisy. She actually seems incredibly selective of the people she protects, in sussing out who is 'worthy' of her protection and if her approval is anything to go off of, she barely seems to care about her so-called little people.
5. I'm not sure I care for how differently she treats the Inquisitor based on race. Especially in a romance. Like, why is it easier for a human noble to get approval from her? That just seems wrong with Sera hating nobles like she does. She also seems to fetishize qunari women, and I've heard that she treats a lady Cadash in a bit of an infantilizing way because of her smaller size. And romancing Sera with an elf? Wow. "I don't usually go for elves. Feels like a bag of chicken necks." .....WOW. WHAT A CHARMER SERA.
6. Her entire romance is a can of worms. I watched vids of it on youtube and I just felt so... unclean. It felt really superficial emotionally, which I didn't care for but then there's all this crap where Sera seems really manipulative. I mean, she'll give a Dalish Inquisitor an ultimatum of 'tell me everything that happened in the temple of mythal was untrue and by the way give up all your elfyness and your cultural heritage or I'm breaking up with you." Or the whole "I'm yelling at you about a nightmare I had" scene was... It just felt really weird to me. I get that the Veil is torn open and stuff and I'm not sure when it happens in the timeline but it just feels extremely unfair and emotionally manipulative of Sera to place that sort of onus of responsibility on the Inquisitor?? Like "You take responsibility for my subconscious please" that whole scene leaves me scratching my head.
I get that dreams can be super scary, I have had a crapton of nightmares, but my go-to response is not to blame my lover for their content s:
I can't even imagine how a post-well scene plays out with a romanced Sera.
A lot of abuse survivors have also mentioned that Sera's romance smacks of emotional abuse and that it can be downright triggering at times, so that's also a consideration.
7. She makes a lot of cissexist and transphobic remarks. Like, what if someone wants to play a transwoman with Sera? I can't imagine that feels good to hear the stuff she says.
8. I do not get her disapproval of putting Briala in charge at ALL. I can get that she might be wary to trust Briala but at the end of the day a noble got murdered (a friggin' empress) and another noble has to bow to an elf, someone "beneath" him. That should be her JAM right there. Killed one noble, took another down several pegs. What the hell don't you like about that Sera?? Oh right I forgot, you hate elves. Of course.
Basically Sera comes along to see the world, has been out there in the world too, but refuses to grow or change and I really abhor that quality about her.
I also do not care for her crudeness and sense of humor. I was hoping for a complex individual that actually gave a **** about helping marginalized people across Thedas and stopping corruption.
Instead we got... a walking fart joke who seems more interested in personal revenge than actually helping out her supposed "friends"
