Let's keep it short!
It is a fascinating show, BUT there are some characters that keep staying in every season and stop me from enjoying.
Some times I really feel I'm wasting time watching some of the scenes.
PLEASE kill or kick some characters in this series, especially "Tokio" or "Rio" or "Arturo". Keeping people who ruin your plan is not logical, Especially for a smart guy like El Profesor. Why would you spend a lot of time to design a perfect plan, and gather a team with members disobeying the rules and tasks? Here you missed a conflict in the smartest character of this series, "El Profesor".
