#1 - One Ocean


Season 1 - Episode 1

Footage of marine life in different environments around the north, beginning with a tropical coral reef which has medicinal properties for dolphins, and is used as a tool by tusk fish. In Japan, a shipwreck is home to the Asian sheepshead wrasse, which can change gender, while in the polar north, walruses struggle to find ice floes for their pups to rest on as climate change takes its toll on the environment.

Yet it's home to some of the biggest and most spectacular creatures on earth. This episode reveals what it takes to survive in this savage and forbidding world. We witness feats of incredible endurance, moments of high drama and extraordinary acts of heart-wrenching self-sacrifice. Every animal in the big blue must find their own unique way to survive.

Blue Planet II - S1E3

#3 - Coral Reefs


Season 1 - Episode 3

Coral reefs are home to a quarter of all marine species. Survival in these undersea mega-cities is a challenge with many different solutions. A turtle heads to the reef's equivalent of a health spa - but she must use trickery to avoid the queue. A remarkable Grouper uses the fish equivalent of sign language to collaborate with an octopus, flushing their prey out of hiding holes. A metre-long, ferocious-jawed Bobbit Worm hides in its tunnel. Monocle Bream retaliate by squirting water to expose its sandy lair.

#4 - Green Seas


Season 1 - Episode 5

Footage of wildlife inhabiting underwater kelp forests, including thousands of giant cuttlefish spawning along a restricted area of rocky reef off the south coast of Australia. Males outnumber females 11 to one, which leads to fierce competition. Larger males use brute force to drive off competition, while their smaller rivals use deception by mimicking the appearance of females. The programme also features tiger sharks hunting for green turtles in fields of seagrass and spider crabs trying to avoid predators while they shed their shells.

Blue Planet II - S1E2

#5 - The Deep


Season 1 - Episode 2

The deep is perhaps the most hostile environment on earth, at least to us - a world of crushing pressure, brutal cold and utter darkness. We have barely begun to explore it, and yet it is the largest living space on the planet. Scientists already think that there is more life in the deep than anywhere else on earth. This episode takes us on an epic journey into the unknown, a realm that feels almost like science fiction. We discover alien worlds, bizarre creatures and extraordinary new behaviours never seen before. We encounter savage hordes of Humboldt squid hunting lanternfish in the depths and coral gardens flourishing in absolute darkness, with more species of coral to be found in the deep than on shallow tropical reefs.

Scientists have even discovered that increasing noise levels may stop baby clownfish finding their way home.

A little about me 👋 I am a marketing student in Paris. I love spending afternoons with friends in a cafe or a park.

But more than anything else, I love watching (.. binging…) series on my computer on rainy Sundays or any sunny day for that matter 🙈

I must have watched hundreds of shows by now, from romance to science-fiction series. Often I like to go back to a show I enjoyed. But I don’t feel like watching it all over again…

I created this website so myself and others could find the best episodes of our favourite shows. As of today, I have about 1,000 shows on the website with votes and rating coming from fans.

Hopefully, you can join me from your sofa and enjoy some nice TV!
