Anne of Green Gables, on CBC (Canada) / PBS (USA)
IMDb; official website; TV Tropes; Wikia; Wikipedia

Based on the books by Lucy Maud Montgomery. I guess this aired on the anthology series WonderWorks in the U.S., in 1986, but I'm not sure if I saw it there or just on CBC, in 1985. I know I read the original book in... fourth grade, I think, but I can't quite remember if that was before or after I saw the miniseries. Anyway, it's about an orphan named Anne Shirley, who wound up, sort of by mistake, living with Matthew Cuthbert and his sister Marilla. They wanted to adopt a boy to help on the farm. Oh well, they ended up loving her, anyway. She was quite an interesting individual. Very smart, an independent thinker, very romantic in a way, but also kind of afraid of romance. Her best friend was Diana Barry. And there was a boy named Gilbert Blythe, with whom Anne had a... complicated relationship. Anyway, I loved the miniseries. And Anne was played by Megan Follows, who ended up becoming one of my favorite actors ever.

I plan on re-watching the miniseries on DVD in 2025, at which point I'll write a proper review.
