Although Winry is a Loser-Machine-Junkie sometimes(she's been called that by Ed Elric cause she's into automail, machanics & other machine stuff) & she can be kind-hearted 2. But what I think is that Winry's expresions r quite comfusin'.
I don't even know if I like her r not.
For Example: What I've seen in the Manga is so different from the Anime, Winry clobbered Al Elric with a wrench then yells at him & calls him a idiot for not understandin' what Ed's tryin' 2 tell him & then tells Al 2 go after him after Ed leaves the room upset while tryin' 2 go somewheres else.(Now that ain't right, especially when Al couldn't remember anythin' of his past & can't hear what Ed's tryin' 2 say 2 him, she's the idiot for doin' these things, that's so stupid!)
And do u see the way she gets mad while she goes swingin' her wrench around r somethin', it's almost like she's short-tempered r somethin'.(Well u know, I think she is!)
She's a stuborn, crazy, weird, 1-tracked-minded, bigmouthed, power-hungry, violent, rude, snobby, idiotic, backstabing, 2 timing, spoiled bratty, LOSER-MACHINE-JUNKIE!(U know, I also thought that she was a JERK just like the other few Anime girls that I don't like & I wanna say she's a JERK but that's good 2.)
And the bad part is that if Winry sees a divice r somethin' that inspired her, she'll take anythin' apart 2 the last screw!
So boo hoo for u, Winry Rockbell!
Wow, you must really hate her. I don't hate her, she is nice, but I like how you express how you feel. Good job on that! 
Winry is like an older sister to Ed and Al. 
she is caring, awesome, shows girl power, and I don't loathe her one bit. She is a very GOOD person. 
Like the episode, "The Untainted Child". I hated her for a little while.
