With Inuyasha...the begining he was so rude and wanting nothing more than to become a demon. Then he got friends and cares about them! (Yes even Shippo!)

Well yeah it has. I've watched the original InuYasha series a number of times so my opinion the characters have changed a number of times just with that one would be Kagome-chanothers would be Kikyou and Kagura-san so by the go around I'd have to say Kikyou and Kagura-san were in my top five by the time I learned their character so yeah I've had it happen numerous times.

Nope. I knew who I liked from the start and who I didn't and it hasn't changed.

I'm not really sure if it counts but I always hated Kikyo to death, now I see she's actually strong and smart. Seriously, by knowing about other anime characters who really suck, I'm sure Kikyo is far away from that.

I used to dislike Kikyo but as the anime progressed I could see how much she had suffered and how kind and strong she was.

At first i hated Kikyo, when she wanted to kill inuyasha (i mean - you are dead, he has new girlfriend, get over it!) but later she changed her attitude and i started to like her.

I liked Inuyasha at first because I thought he was cute (and I was only 8 years old) But now I hate his guts and I wish he would've died. He is so rude and a total liar!!! He pretends to care about his "friends" but is really just using them to get what he wants. I despise him.

Kikyo, Miroku, Kohaku, Sesshoumaru, and even Inuyasha. My opinions of these people became more positive over time.

Oh and I forgot Kagura and Kanna. Their final act episodes were so sad...
