The magical green seas
9 December 2017 | by TheLittleSongbirdSee all my reviews

David Attenborough, as has been said many times, is wholly deserving of being called a national treasure, although it is a term he happens to not like apparently. He has done so many treasures and even his lesser output of a long and consistently impressive career is still good.

Absolutely adore the first 'The Blue Planet', one of my favourites of his, so was psyched to hear that there was a second 'Blue Planet' series. Luckily, 'Blue Planet II' turned out to be every bit as amazing, easily a highlight of 2017 television and one of not many programmes that year to leave me completely transfixed and wanting to see the whole lot and looking forward to it every week. This is saying a lot, seeing as apart from the odd gem 2017 has not seen me watching new television by habit, often find myself seeing re-runs or films more.

OK, so 'Blue Planet II' may not be as ground-breaking as 'The Blue Planet' and not everything is new here. This doesn't matter, because 'Blue Planet II' is just as beautiful to watch, non-stop transfixing, educational, inspirational and emotionally complex. "Green Seas" is nothing short of magical.

Visually, "Green Seas" is a wonder and a feast of gorgeous images. It has gorgeous scenery and rich colours, while the animals and marine life are captured in all their glory. Standing out even more is the photography, the underwater sequences are just as stunning as 'The Blue Planet' (unequalled when it comes to underwater sequences).

Particularly standing out are the sea otters floating on their backs and the baby sea dragon taking its first swim, truly beautiful. Then one is absolutely shocked at how something so wonderfully weird and intense as the scene between the pyjama shark (nowhere near as cute as its name suggests, it's pretty vicious actually) and the octopus was filmed, that is a scene in every way that stays with the viewer forever.

While not with the involvement of George Fenton, the music here soars, rouses just as much and touches the soul just as much, definitely worthy of cinematic quality. It not only complements the visuals but enhances them to a greater level. Some have found the music and sound effects too bombastic and intrusive, not for me.

Really can't fault the narrative aspects in "Green Seas" either. There are things already known to me, still delivered with a lot of freshness, but there was a lot that was quite an education. Found myself learning a lot about the mystery and beauty of the ocean and the marine life that inhabits it.

Attenborough's narration helps quite significantly too, he clearly knows his stuff and knows what to say and how to say it. He delivers it with his usual richness, soft-spoken enthusiasm and sincerity, never talking down to the viewer and keeping them riveted and wanting to know more.

"Green Seas" highlight is undoubtedly the aforementioned pyjama shark and octopus scene, the only other scene to have that same amount of impact on me in a series full of emotional complexity was that of the whale carcass in the second episode. "One Ocean" also had the bottlenose dolphins and killer whales, but that was a different feeling.

Nothing episodic or repetitive here. Instead, it feels like its own individual story with real, complex emotions and conflicts. One roots for the animals, whether prey or predator. The behind the scenes footage "The Deep Blue" brings honesty and humanity, what the crew go through and how they work against sometimes volatile conditions makes the viewer feel admiration for them.

Summarising, a magical episode of a 2017 gem. 10/10 Bethany Cox
