Really liked this one! It is fairly simple but showcases how well our main cast work, some brilliant Hartnell Moments sprinkled in it and bam you got a very good 2 Two Parter. Personally, the idea of something going wrong and Ian & Susan going a bit mad is great, Carol Ann especially does great work with it. I will say if it was longer it probably wouldn’t have worked as well as it did, always a nice change of pace after the rather long 7 Parter “The Daleks”.
