Merlí was simply one of the greatest series ever made. Besides the grandiosity of Merlí, the rest of the cast was outstanding, and the script made them flow naturally between each other. The story was believable, emotional, deep and it's all about character development.
Merlí. Sapere Aude fails in all this. It seems to be a gathering of non-believable characters put together to spin around Paul. It just doesn't connect with anything. None of the characters connect the viewer.
Where is the connection to Merlí? The series is set 3 weeks after the Merlí story ends, and it's like that universe ceased to exist. Besides from Bruno and Calduch, which make shallow appearances. Where is Tania? Where is Bruno's sister? Where is Ivan? These people can't just disappear from one day to the next, specially when the story's main character had such strong connections with them.
The script fails to achieve a new story and tries too much to separate itself from Merlí. It just doesn't work. It's disappointing to see how the same script writer can make something so beautiful as Merlí and fall down into something that no depth at all.
I'd much rather see a Merlí Prequel than a Paul sequel written like this.
