I don't know how they achieved the look but they have these wonderful glowing colours through the show, sometimes blurring slightly which also adds to the effect. Nice dark shadows too.

The influence of Art Deco is there in the ship set designs and maybe the clothes too, all of which are stunning.

And the story and acting: I must say I don't find it off-putting like I do nearly 95% of the British-American-Canadian-French-Indian and other productions. Basically, I cannot watch hardly anything that comes off Netflix or Hollywood today. Maybe this Spanish series is getting something right.

I'm into the third episode, so unlike what someone said, the first is not the only good one, imo anyway. So while, the plot etc. Is nothing radical it's far from the worst Netflix series, and far far ahead of the others. It's not reliant on realism, randomly shot, quick shaky camera, Euro Cannes style film making which irritates with its total pretension.

In short, beautiful, easy to watch, while not really insulting your intelligence or emotions.

I only saw Season 1 and that was enough. I wasn't watching for the twists which actually put me off. It's not like I want to keep watching a series till the end of time.
