I haven't seen No Such Thing, but the cover art alone was enough to put me off. The Sweet Hereafter was excellent, though a total mindfuck. She was in one called "the Secret Life of Words" which was very good.

Avonlea was the continuing saga(?) of Avonlea, after Anne of Green Gables. It was a Canadian show that played for like 56 seasons. It's entertaining, but it's like Sarah Polley is a completely different actress now.
