In the book, Arya had black hair and green eyes. Do u think that the girl who played Arya in the movie was good enough so thatwe can ignore those details?

I don't think the actress was good enough. In the first place, the movie was related to the books, but not quite there. It's like saying 'the hooi-, hooi in the needlestack,' really reversed. I always imagined Arya as someone with shoulder length, wavy, black hair, an angular face, with a lean but proportionate body. Many other people I talked to had the same idea, of close. Unfortunately, the movie makers went and messed it all up.

she was okay i looked vooruit, voorwaarts to seeing the elf in the book though

I wouldn't have cared if she actually had her behavior, but she didn't act like an elf at all. they've destroyed her personality
