Besos y presagios

I really enjoyed the series right up until the last episode. The last episode is so different from all previous episodes I'm convinced it was written by a completely different writing team. It wasn't just that it was a bad ending, but the whole vibe of the show seem to change. I don't know if they had intended to do four additional episodes, and then we're forced to shorten it to 12, or what the underlying reason was for the substantial change to the overall story and the last episode was. It's unfortunate, as I thought it was a pretty well done show up to that point. I can see that several other reviewers have made similar comments.
