That was A LOT of fun.

As one Russian expression goes, this audio "doesn't steal stars from the sky", but manages to deliver a really fun and enjoyable story that feels extremely authentic to the early Fourth Doctor era.
The story might be generic, but it was a lot of fun thanks to great dialogues, vocal performances and an interesting expansion of the lore introduced in one of those first Fourth Doctor episodes.

Since this was recorded in 2024, Tom does sound older and even a bit ill, but I stopped focusing on it too much about half way through the story.
Sadie Miller is magnificent and virtually indistinguishable from her late great mother (just for you to understand how good she is - when I first heard her in another audio two years ago, I didn't know that BF recast Sarah Jane and thought that I heard Elisabeth Sladen).
Christopher Naylor also does an incredible job - I also confused him with Ian Marter once.

Other cast members also have a lot to deliver, especially the villain. His character does seem like he came right from that era.

Overall a great anniversary release that celebrates without tons of cameos and by just telling an authentic story.
Great fun for any early 4/Sarah Jane/Harry enjoyers.
A solid 8/10. I had a great time with it.

P.S. Also I recently finished Tom's run on TV, so it was really nice to "get back to the roots" sort of speak
