Once the human mind has been inhabited and infected, the parasites are able to take control of it and sprout horrifying powers such as razor sharp tentacles from the host's head.

However, in Su-in's case, she's still in control of her mind, which makes her a valuable asset to a special task force, known as The Grey.

One impressed anime fan wrote: 'Well done to especially those who've watched the anime. There is a build-up for a second season especially with a very familiar character showing up at the end.'

A final viewer commented: 'As a fan of the maxim, the last minute of the show thoooo[sic].. don't be showing us that and not giving us season 2 Netflix.'

It comes as Netflix fans have recently become 'hooked' on a new foreign language crime drama.

Wrong Side of the Tracks follows an army veteran as he tries to exact revenge on the Madrid gang which kidnapped his adopted granddaughter.

All 32 episodes of the show - named Entrivas in Spanish, after the neighbourhood where it is set - are available with subtitles on Netflix.
