In July, Netflix launched an exclusive show called Mako Mermaids. You don’t hear about it as much as the most of the other Netflix originals, but it’s available to stream, and it has its audience.

In fact, Mako Mermaids came with a built in audience, much like Arrested Development, another Netflix “semi-original”. The show is a spin-off of popular Australian show H2O: Just Add Water.

The show debuted with thirteen episodes, and last month, it was announced that an additional thirteen would become available on September 15th, which is this Sunday.

Titles for the forthcoming episodes are: Battlelines, Sirena’s Secret, Truce, Moon Ring 2, The Trident Job, Where’s the On Button?, Nowhere to Hide, Aquata Returns, Evie Times Two, Zac’s Choice and Trust.

Netflix also debuted another original this week – the Ricky Gervais comedy/drama Derek. While dubbed a “Netflix Original,” it actually aired earlier on Channel 4 in the UK.

Here’s more of what you can expect to hit Netflix in the coming week.
