Yes, there is a spin-off/sequel to Narcos - it's called Narcos: Mexico. While the original Narcos series focuses on the infamous Colombian druglord Pablo Escobar and the Cali Cartel, Narcos: Mexico shifts the spotlight to the rise of the Guadalajara Cartel in Mexico in the 1980s. In the show, we follow DEA agent Kiki Camarena in his mission to dismantle the Cartel. The series starts as a parallel story to the original Narcos timeline, but eventually intersects with the original series by the end of its first season. As of 2022, Narcos: Mexico has three seasons, with the final season focusing on the events after Felix Gallardo’s fall. The spin-off is said to explore the conflicts within the Mexican cartels and the political crisis of Mexico in the period. So, if you loved Narcos, Narcos: Mexico is certainly a good extension of the story to continue with. However, keep in mind that it maintains a somewhat different tone and setting, focusing more on the widespread corruption in Mexico's political and law enforcement agencies during the era. On another note, Narcos: Mexico also stands alone as its own show, so there's no strict requirement to have watched Narcos prior to diving into Narcos: Mexico. However, watching the original series will certainly grant you a wider context and deeper comprehension of the storyline. Enjoy the binge!
