at first i thought Dawn was soo annoying and kind of a spoilt brat gettig her way all the time,plus always hanging around with Buffy if i was Buffy i'd get well annoyed.when she does that whole 'get out,get out,get out' thing i was just like please someone shut her up,but i guess i can understand why she was acting like that.when Glory started to hunt her down i started to like her more because she started to act more grown up and take responsibilty for things and she was willing to give up her life to save the world,which takes a lot of guts.
although in season 6 she did start to get a bit whiney again but i cant blame her because she could tell that Buffy wasnt herself and she wasnt getting to bond with her and do sister things,i mean Buffy wasnt the only one who experienced a death Dawn had to go through that herself,and Buffy just tried to deal with that herself and not include anyone in it.i liked Dawn the whole way through season 7 though.overall i dont think she was a bad person she could just be a little bit annoying at times,which is kind of like her sister,cos Buffy can be annoying at times as well lol
