Talk about the wrong message to send
I'm watching A Wrinkle in Time on ABC right now and Charles Wallace is being tempted by the Red Eyed Man (REM). What a screw-up. Maybe I'm wrong in remembering this, but in the book it was Charles Wallace's own arrogance and over-confidence that allowed him to be taken over for a time.
In this, its making it look like the REM is tempting him to evil with knowledge. A giant encyclopedia fascinates him, followed by math, and then learning other new skills. And as he learns more, he starts to hurt those he cares about. This is just a great message to pass onto our kids, knowledge is evil and corrupts. For all those who say that its not bad for the age group its aimed at, I would argue that your children would be better served by having them read the book rather than watching this letdown.
