Verdict
Homo Aqua was a very strong start to The War Between the Land and the Sea! I watched with intrigue and excitement on broadcast alongside a rather less enthusiastic partner of mine. She likened things to Avatar which she's not a fan of but thankfully I thought this was really good and I'm excited for more to come. I'm almost disappointed by the fact it has been released as a double bill because I've had to stop watching now to write this blog! My appetite for the series was wetted this morning in watching the new feature-length version of The Sea Devils and I like how the opening titles in that edition followed suit with how things opened here. It certainly didn't feel like Doctor Who whilst being set in the Whoniverse and I think that's a really good thing. It needs to have a different feel and that was exactly what happened here. I thought Russell Tovey was actually outstanding in the lead role as Barclay and it's fun to see how much his character has changed already. The fact he got to be part of the initial mission to Dragonera by mistake and an admin error still listing him as Together Trevethick's replacement was wonderful and he portrays the humour so well. I thought our reintroduction to the Sea Devils in the form of the updated name of Homo Aqua was surprising in that we started with a corpse (apart from the brief moment before one was shot in the fishing net). I remember seeing the leaks of the updated design for them and feeling like it was pretty questionable, but seeing it in action I thought they were fantastic. The carrying of the staff is also a really good touch that brings some more fear factor to them. I could probably have done with less emphasis on translation in the episode so once Salt emerged for the peace talks I was delighted that this was done away with. No such issues when the TARDIS is around! Barclay touching upon meeting the Doctor briefly when at the UNIT Tower was just enough of a nod to the wider Whoniverse without dwelling on it and even when UNIT took command of the peace talks with Kate at the head it didn't feel like any prior knowledge was required which is good for the first episode of a whole new series. I thought the impact made by General Austin Pierce was sublime and that voice is just booming! I hope his role isn't diminished moving forward by the arrival of Kate, even if she is a welcomed familiar face. It's always fun to see Trinity Wells back and just gives everything that little bit of continuity, but the imagery of the news reports in showcasing the Homo Aqua rising from the depths of the waters all across the world was magnificent. I was so impressed with the visuals here which I don't often mention but they really were striking in the best way. Barclay's family life was good to explore and I'm sure it's not the last of it but his position as a civilian witness is great stuff. He feels like an everyday person and that's exactly what's required here. He was shocked by seeing death and the way the Corporal and Captain were pulled beneath was brutal. It's the only act of defiance we've seen from the Homo Aqua but it said a lot about their capabilities! I like how Barclay's religious crossing of his chest when seeing the Sea Devil corpse was mistook for respect and that meant he was the one Salt wanted to represent humanity in their talks. That took everybody in the diplomatic setup by surprise, including Barclay himself! That 'okay' line at the end of the episode was done perfectly. Overall, a lot of set up but that's always going to happen in a new series like this, but as a veteran fan I'm already well versed in what's happening. A lot of tension and some intriguing politics with some glorious design and imagery. Not bad at all for a series opener!
Rating: 8/10
