It started really well. It seemed like a good and interesting series to watch but slowly and gradually the writers killed the best characters and the storyline. It's obviously based on fiction and nothing to do with real historical events.
By series four I was tired of Doña Carmen her mafia boys, and her never ending power.
Some of the characters were well written, and the hair, wardrobe and make-up were excellent but the end was "awful". The writers lost their originality here.
