The ending
I just finished watching the entire series. Loved the show except that they kept trying to add more and more intrigue. The show would have worked better with fewer side plots had they stuck to the bigger plots only; the death of Julio's sister and finding her murderer; the 2nd son of the father Carlos and his role in the whole story; the serial killer and the part that Diego and the mother Teresa play as the villains. Andres finding out he was the illegitimate son of the hotel owner, Carlos Alarcon, that story should have been more fully developed at the end since it played such a large part in the entire series. They missed their mark even though I was absolutely obsessed with the show until the middle of part two. Then the whole continuation of more murders, more intrigue, more bad guys was just too much. There was a little more lightness, fun in the show in the second half but it could have used more comedic relief. They should have developed the story between the Housekeeper, Andres' mother, and her maitre d'. That romance could have been fun and worked well, instead they ended it by sending the maitre d' out of the story very quickly.
The ending was very disappointing. I guess one always wants to see the bad guys get their justice in equal measure even though I did not expect that from a Spanish script. They tend to darkness rather than to romantification (if that is a word, if not, I coin it.) I expected a dark ending but was not prepared for such an abrupt one with no goodbyes to our beloved characters. It is almost like watching a play where at the end you want to stand up and give the wonderful actors a standing ovation. You want to say your goodbyes to the wonderful actors that gave us such a thrill when watching their work. I must admit that all of the actors were wonderful in their parts. One hated the bad guys and loved the good guys. The good guys even had their imperfections which was perfect.
Therefore, the ending was disappointing. Unless of course they planned to follow up with another series based on the reappearance of their characters as some having lived after the final tragedy. I will not spoil it for those who have not seen the series yet. There has to be a way to write a better ending without over romanticizing the ending and yet leaving the audience feeling satisfied that they have concluded their relationship with the show and it's characters.
