Just finished watching the show and Mikasa is my favourite character of all time. Why do some fans hate her so much?

Serious question like I just don't get it at all. Most of the critiques I have seen of her just make no sense at all. She's a cool character who had really good character development and writing. She's also the most likeable out of everyone imo because it really seems like she always has the best interest of others at heart and she's smart. Plus she has the best and most real philosophy in the show which is really impressive seeing as how many great philosophy their are in aot. I just don't get it lol
