A gem of a two parter. Being shorter than most stories makes this such a tight and strong and easy watch. It's also the debut of Victoria as a companion, who in my opinion is more enjoyable to watch than Susan.

• I've always much enjoyed Vicki as a companion and her introduction solidifies that
• It perfectly takes use of its time and doesn't prolong it any longer than it should
• My literal only gripe is the small minor details that could help piece everything together, like hints that other crew members were still alive or there being signs of the planet's original inhabitants being killed. Something to level up the world-buildin
• This is a story that feels a little predictable, but there's nothing wrong with the obvious incoming twist it works well, and it earns it
• It's a story that captures why I like the 1, characterised beautifully

I like this serial. It benefits from being on the shorter side. The story is concise but interesting. The twist reveal is  set up nicely and done very well.

I immediately like Vicki, and not just because she looks like my favourite cousin. This is a great introductory episode for a new companion. I love how she immediately trusts the Doctor, how much she cares for the local wildlife, and her willingness to forgive Barbara despite killing her pet.

Unlike most classic stories yet to come, this serial doesn't immediately forget about Susan. The Doctor is clearly still feeling her loss. I appreciate that.

I wasn't a huge fan of the episode.

So yes, at the beginning, we see a new side of Doc, after Susan left. But it's not explored enough! Rare example of an episode where the storyline isn't explored enough.

One more episode to consolidate everything would have been acceptable.

This episode is worth 6/10

One of the best paced Hartnell Stories, easily. It’s a stellar Outing and introduces Vicki superb. Maureen fits perfectly in the Tardis, and it’s clear that the writers know a lot more how they deal with her than it was sadly for Susan the case. She is also a favorite of mine so that’s a big win too, but yeah the Story is amazing. I love the faster pace, I love that this was made as two-parter and therefore can build tension faster. I love the Twist at the end with Bennet and overall I think it’s super underrated overall.

I also very much enjoyed the end scene where our three tardis crew members agreed to take vicki with them, it’s such a lovely scene. Really this sets the mood for the rest of this lovely season’s filled with a spirit of adventures!
