Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

It really made me laugh, but for some moments I was tearing up because I could relate so much.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

This movie tries so hard to be funny, yet it falls flat every time. Just another example of recycled ideas repackaged with women in an attempt to appeal to a certain audience.

More than having an amazing screenplay, the animal costumes look so real. Especially the surfing dolphins, they did a great job casting actors that could both surf and pretend to be dolphins at the same time. Great production quality!

Many movies and television series claim to push the boundaries. This one really does. As the material about the making of the series (at the end of each episode and online) shows, the four years it took to make included a record depth for a manned submersible dive in Antarctica, round the clock diving to make sure they did not miss a once-a-year event at a remote island, coping with huge sharks attacking the crew's submarine, deploying a range of novel filming technologies, and taking so much time under water that they were able to record behaviours never seen before. Around a thousand hours of shooting were needed for each hour of programme. The results are genuinely sublime, with an astonishing range of natural wonders captured by photography that is surely peerless in its beauty, range and consistency. Skilful editing and commentary helps bring each of the subjects to life. Evocative music and sound effects may irritate some but for me, and I expect most others, these add to the impact. The conservation message is there in part in most episodes, emerging into its own in the final episode, but really the whole series is a uniquely powerful plea for the conservation of the oceans. Beyond that there is not much to say except "see it".

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. 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 (a strong contender for the best BBC produced one and the best nature documentary series) and one of not many 2017 dramas/series that had me looking forward to see the entire lot. 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.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.Visually, 'Blue Planet II' was, as it was with 'The Blue Planet' and the best of Attenborough's work, a wonder. 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).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.Really can't fault the narrative aspects in 'Blue Planet II' 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 and after watching the full series it honestly felt like the series taught me a lot about the mysteries of the ocean and the marine life that inhabit it. One episode explores the consequences of environmental waste and, while it may seem out of place for some, it was very much relevant and important and well-handled.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.'Blue Planet II' has a lot of effective scenes. It's not easy picking a standout, because there is a lot of emotional complexity here. There are shockingly gut-wrenching moments, especially the whale carcass (a strong contender for the most shocking scene of 2017). There are emotional moments, such as the mother with the dead calf. There are tense moments like the octopus and the shark. There are awe-inspiring moments like with the dolphins. There are also moments of great surprise, like in the first episode where one expects a bird to fall prey to an underwater predator but instead something that one cannot believe was able to be filmed let alone found happens.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.In short, utterly amazing and calling 'Blue Planet II' a must watch does it no justice. 10/10 Bethany Cox

This series had me reaching for the thesaurus as I simply don't have enough words to encompass its utter brilliance. Time after time I caught myself exclaiming out loud "OMG" or "whooaaah" - inarticulate I know but so overwhelming is the impact the brain cannot cope. The only documentary to ever come close in Planet Earth II from the same source - it's difficult to imagine anything topping this duo, ever.This time around there is more storytelling to accompany the visual feast, and its a welcome enhancement. The sad and devastating truth is that this may be the last time the ocean looks this way - if we let it degrade our descendants will rightly despise us.You must see this - there are no excuses.
