Great budget and scenery, but horrible writing.
There are plenty of ridiculous loopholes in the series' logic, and the plot armor makes it very cringeworthy. Nobody can aim straight, and the bullets only hit when convenient. By the end of the 5th season, the real spanish government would have squashed the protagonists 100s of times already.
However, there are some good episodes with less bs. Additionally, each episode is action packed with good acting at times and filler at others. Overall, this is a good series if you are into Hollywood stereotypes but not so good if you like realism more.
