Watched it front to back in Portuguese a while ago. It is one of the few series available in European Portuguese, most are Brazilian.

I'd say it was time well spent, it is an entertaining and capturing thriller and you learn a bit about a certain era of Portuguese history.

What annoyed me a bit was that it had many small period inconsistencies. Little things like modern buildings, modern cars visible in the background, the Yamaha grand that did not yet exist in 60s and so on. Where it shines are the landscape shots.

RTP (public TV network, which also produced Gloria and Turn of the Tide, the two Portuguese Netflix shows) is unfortunately the only network investing in this type of fiction television. The other two big networks unfortunately only seem to invest in soap operas, which run for 600+ episodes and are very formulaic. It’s sad because RTP has definitely made some very good stuff (and they’ve been collaborating with Spanish networks on some cross-border shows, there’s a few they’re pretty good), but you can tell that these things suffer from relatively low budgets.

That’s why turn of the tide came as quite a shock in quality compared to the rest of the shows - Netflix actually put a relatively high budget into the show, which just allows them to dedicate so much more time to these little things.

When watching it, the thing that would consistently real the period piece illusion for me were the modern cranes that you could often see in the Lisbon scenes.

Another great one, based on the same direction approach as Casa de Papel, is Rabo de Peixe.
