Perhaps the best Lost In Space episode of them all! Very well written and directed, and of course very well acted by young Angela. As with other outstanding episodes, note the dramatic use of light and dark, especially in the scenes behind the mirror. Angela’s expressiveness is particularly moving in the last scene by the mirror, as she realizes the boy is not following her out, but doesn’t understand it’s because he can’t, not that he won’t. Truly a heartrending scene.
