Simon Guerrier is one of Big Finish’s most dependable writers. The Outliers is a gripping example of his talent with the Second Doctor. 10/10.

Blogtor Who

Writer Simon Guerrier has captured both the feel of the time (aided by some great sound work and music from Toby Hrycek-Robinson) and given some more modern motivations to the antagonists. Another solid release in a range fast becoming as essential as the monthly releases. 4/5

Cultbox

It very much feels like something from the period, with hints of both The Macra Terror and The Underwater Menace from time to time – and Guerrier has a lot of fun with a small segment looking to the future… 9/10

Sci-Fi Bulletin

You have something that feels in tone like an original second Doctor story. Guerrier even talks of colours and sets he envisages would have been used if this was on TV and how that influenced his writing when he is talking in the interview extras. But this also has some pleasing suspense, horror and modern high concept elements that are layered in. What you get as an result is a well-integrated hybrid of old and new Who. A must for your 2nd Doctor collection! 9/10
