War of the Sontarans

The Crimean War. The light Division are going to war with Sontarans who have decided to invade during the crimean war. I like the more classic looking Sontaran look and them riding horses. The Sontarans are across time, Dan is in 2021 while Yaz and Vinder have discoveries at the Temple of Atropos learning about what the main villain Swarm is doing whom I forgot to mention in my Halloween Apocalypse review.

Why is it that I have like nothing to say about these episodes.
