She trekked after his mother to steal him back. Had it been his mother, she'd have been killing his mother no?, as it was, she spent years wasting her life chasing her windmill, and was unfortunate enough to find it. (Unfortunate for all three).
I think the only sad part is the fact that the ending was entirely predictable, they should have gone for something else other than what we have all seen before.
I hope I'll be able to make animated movies like that someday :ermm:. I liked it. Might name a character after her in Skryim. "Sintel The Regretful". :thumbsup:
