You're reasoning is very stupid
the inconsiderate b**ch died on me!
that makes me angry a bit.
the only thing she was good for was her overdrives
also is very stupid.
This game isn't about the battles it is about the story.
Having said that I also didn't love Aeris though I do like Aeris, she plays a big part in the story and is a nice character. She isn't a great character but then again are any of the characters in FF7 great? No......
She was alright.
If aeris was never there would cloud have even bothered trying to save the planet? No...
