Benji Wilson Daily Telegraph (UK) Dec 11
3/5
Perhaps the overt environmental message is meant as a prompt for the younger generation, but if so, it is all the more misguided – they are far more aware of what their parents have done to our planet than their parents are. Go to Full Review
Ben Dowell The Times (UK) Dec 8
4/5
This is a well-meaning lecture about environmentalism, but it is wrapped in a lean and propulsive whole that makes the inevitable moments of pious sanctimony, which all but capsized the mother show, more than bearable. Go to Full Review
Ed Power Independent (UK) Dec 8
2/5
It’s always been a reliable rule of thumb that the more UNIT in an episode, the more boring the results. That lesson is delivered all over again in this OK-ish mini-series that has decent production values but suffers from a consistent crisis of tone. Go to Full Review

(I consistently thought in the back half) 'I don't like the choice that you made, but you're executing that choice pretty well.' Go to Full Review
Barbara Ellen Observer (UK) Dec 15
As the five episodes unfold, the series markedly improves, weaving an interspecies love story into the environmental themes, and with a darker, more urgent tone than Doctor Who. For those who persist, the final moments are poetic and beautiful. Go to Full Review
Alison Rowat The Herald (Scotland) Dec 12
Davies has a lot of points he wants to get across about humankind’s trashing of the planet, but he doesn’t do so heavy-handedly. He never forgets to put the thrills in, and a few good jokes besides. Go to Full Review

Chloe S @RT33488535 Apr 12 I’ve rarely been this disappointed by a series that started with so much promise. It features a powerhouse cast,including Russell Tovey and Jemma Redgrave,who are completely betrayed by a script that abandons logic in the final act. The real villain here wasn't the sea creatures; it was the writing. After building a complex political and ecological thriller, the show resolves everything with a genocide plot that makes zero sense. The mechanics of the Severance virus are a mess,if the protagonist is a carrier who has close contact with the lead Sea Devil, the internal logic dictates the ending shouldn't even be physically possible. To make matters worse, the show sets up a global environmental catastrophe with the melting ice caps and then just... moves on? It ignores the very physics it established to chase a cynical, hollow "victory" that leaves the audience feeling like they wasted their time. A grim, logically broken conclusion to a series that could have been great. See more Andersen O @RT16626658 Mar 14 enjoyed watching this, just the ending not what I like. See more Mark H @Shanobian Feb 17 It's alright. Interesting premise but a clear left wing pandering propaganda poster disguised as an interesting invasion story. The plot builds and builds tension promising action but aside from one boom nothing happens. Then the ending comes so left field that its clear they didn't know how to end it, it just ends. No big payoff, nothing explained just a catastrophic terrible ending that will make you wonder why you wasted your time. See more STALLONE T @Sta89 Jan 14 Its one of boring series,like sea pple dumps tonne of garbage to land and next episode the entire land is clean how?,you are in the bottom of ocean where the sub almost collapse due to pressure and next min you survive.. you swim with min until surface.. how Then how do you fall inlove just min and ans you kiss the fish... See more DanTheMan 2 @DanTheMan2150AD Jan 12 Arriving a full 9 years on from Doctor Who's last televised spin-off, The War Between the Land and the Sea finally makes up for lost time. Visually, the production is serviceable but equally inconsistent, some sequences effectively convey scale and menace, directed adequately enough by Dylan Holmes Williams; others suffer from lacklustre CGI, laughable staging and Lorne Balfe's overly dramatic scoring, loved the Heroes needle drop though. I got strong Children of Earth vibes throughout, almost as if there was a conscious effort to replicate what made that series so good. However, it lacks the big emotional hook, mature tone and Euros Lyn's impeccable direction of that monumental miniseries. As harsh as it may sound I'm being, The War Between the Land and the Sea is very well-intentioned, timely and conceptually strong while being genuinely great at the same time, reframing the classic Sea Devil mythology through a modern ecological lens. See more David H @Southseacoast Jan 11 Well thought out, great pleat, good acting and a brilliant end. See more Read all reviews
