What a shame!!, it could have been very good. They tried, but this series does not reach the quality it deserves at all, on the contrary, they screwed up very badly in this one.
To be honest, I started seeing it only because of Luis Tosar, a great actor that I really like. He only has kind of a supporting role in this case.
The series is full of inconsistencies, badly edited and full of cliches, simply trying to copy good criminal series without reaching the level, not even close!
All imaginable cliches go by , corrupt family, corrupt police chief, characters you won't worry about,
pretty girl showing navel who cares only about sex, power and money, police infiltrator,
sex and meaningless scenes just to fill minutes...
... Chinese mafia that is almost laughable in this case, Gym with guys who want to play tough but aren't convincing at all, blonde woman with a wig who tries to be scary,..the wig is! , girl with a motorcycle delivering pizzas to spy.. This is almost a comedy, and yes, it even makes me laugh.
And the end... ayayaii... very badly done and in a hurry.
As for the title, I would have translated it as 'sky is the limit', and not high sky. Strange translation.
I have some positives.. the action is not bad, and in general it's entertaining and not a long series, thank goodness!
So if you like poorly made and poorly edited , the kind that don't matter and we forget quickly, and you only see them for the action, this is the one for you.
Finally for the creators, Mr. Calparsoro and Mr. Guerricaechevarria, since you spent the money on this,
you could have worked better and harder on a good series because the idea is good.
Good Luck for the next one! And please don't waste time and money making a second season.
