Very good performance by Katie Stewart as the put-upon Meg, and by David Dorfman as the child genius Charles Wallace (although I think he is a bit too cute: I remember Charles Wallace as being --difficult--in a number of ways). Alfre Woodard was also very good as Mrs. Whatsit, although of course very different than I visualized her from the book. Allison Elliott was quite effective as the "spacy" Mrs. Who, and Kate Nelligan not quite scary enough as the formidable Mrs. Which. Beautiful special effects, especially the first "Tesseract" sequence, which I thought visually expressed Ford Prefect's description of a similar phenomonon as "unpleasantly like being drunk." Although it must be said that once the phenomonon was established, the later sequences were a bit longer than needed. I was surprised to see how "1984" influnced the evil-dominated planet of Camatoz was, but of course when I read "Wrinkle" I had not yet read "1984."
As the network proudly advertised, the show was family-friendly, with no sex, blood, or cursing, which is not to say that it wasn't occasionally scary or violent. Suitable for imaginative children, but may be too intense for the quite young.
*Note to above: Apparently, the show was actually a Canadian-produced mini-series that Disney picked up for US televison, so not actually a Disney product--which didn't stop Micheal Eisner appearing during one of the commercial breaks and inferentially taking credit--.
