Loving this show!! Binged the first 3 episodes, can't wait to see what coming next. Got to the end and still loved it... however... WHY do writers/producers/directors insist that straight people automatically become gay, 30-seconds after meeting a gay person? What kind of gay porn fantasy is this that they insist on perpetrating to everyone? Life doesn't happen this way.. never has, never will.

[Movistar+] It knows how to build tension with a measured structure and an interesting use of the cliffhanger, although some secondary plots feel forced. The claustrophobia of the investigation inside the submarine is cleverly alleviated with a parallel investigation on land, enhancing a narrative that throws out some political ideas without hindering its thriller status. Season 2 is clearly inferior, much more predictable and implausible than the previous one, with frankly bad episodes like the one that takes place during the kidnapping. The series has more difficulty this time in making the main couple empathetic, and the development of false culprits is boring and predictable. Outside of the submarine, the show sinks into mediocrity.

An interesting and timely premise that offers suspense paired with national security gamesmanship. Excellent cast, great performance, perfect balance between personal and global storylines. It will take awhile for this BBC series to get to our side of the pond but I encourage folks to watch for it. I give this series an 8 (great) out of 10. [Crime, Espionage, Drama]

Season 2 was dreadful. A confused mess, everything apparent from the beginning with stereotypical bad guys and virtually no good guys.

Stunningly good thriller partly set on a British nuclear submarine. A detective faces continued obstruction as she investigates a murder - a murder that isn't going to be the last. Attempts are being made to sabotage the ship, and the Russians are circling. Tense and involving.
