So why can't the BBC make science fiction programmes like this? Simple set pieces, well written dialogue and some potentially good ideas, all rarely seen in this made-for-video release. A waste. The most stand-out episode is the final segmant featuring Sophie Aldred as a stranded pilot who realises she's running out of oxygen. Aldred gives a fine performance of what appears to be a mature version of her DOCTOR WHO character, Ace. All rounded off with some behind-the-scenes information make this a worthy purchase.
