I was ready to expect at best a fine story, at worst a forgettable one, but to my Surprise, I thought this one was actually excellent! While I can see why some wouldn't think much of it, to me, it clicks all the right Buttons 5 and Nyssa have such an intriguing Chemistry here, their Conversations are for me, easily the Highlight of the Story. I also quite liked what they did with the Thals here, I must admit ever since the original Daleks Story and Genesis, I don't really think much interesting has been done with the Thals, so this one was a delightful surprise to me. And while I am big Fan for the Daleks in general (I just think they are great), I appreciate it quite a lot how they handle them here, in particular when the Emperor asks 5 for his Help was something I didn't expect but quite enjoyed. Now, is that the most original Thing ever you can do with the Daleks? Of course not. But I liked it. I will say I couldn't care less for the Mystery Aspect of this Release and I thought Episode 4 kinda lost me a bit, but I genuinely thought the first 3 Episodes were quite engaging and a pretty good Dalek Story!

Some great performances, especially by Peter Davison don't elevate this story that gets lost in a tortured, convoluted plot built around another annoying time paradox and resolved, again, by the whole story un-happening.

This format shouldn't ever feel rushed, it's too long (I really don't like the classic who format sorry not sorry. The final part was super messy especially, the resolution felt so rushed. I loved Nyssa in this, getting to use her scientific background was good and the conflict with the Doctor / Adric mentions were fab.

It was a brilliant listening experience and I would urge this to be a must for listening. I love the simplicity of this story and the rippling effect it has. I can only imagine how amazing this would have been as a TV story even back in the 80s.

The call backs, and building on a previous story was good, I was interested and invested in characters, and enjoyed the Fifth Doctor and Nyssa dynamic. Still, not as exciting as most Dalek stories, but this was an improvement on Big Finish's Dalek entries so far. joeymapes21 View profile Like Liked 1 Show All Reviews (14) Open in new window Statistics AVG.
