This is a review for Fathom, the prequel to Derelict.As everyone has noted the sound design is wonderfully atmospheric. The echoing booms of eddies against the station walls and the clang of machinery. You feel like you're right there with 19,000 feet of water waiting to crush you.I love a good competence porn story. Give me an unraveling disaster and a character with brains and gumption sifting through and discarding solutions, and I lap it up. The reward is not in characters being automatically right, but in being able to follow their thought processes. Especially, when something goes awry and they have to correct on the fly. How are they going to get out of this situation? I had my heart in my throat at moments wondering if the characters would survive because the show sets up scenarios where the odds seem so slim. But the writers do the work of explaining how and why one can survive, so that it turns dumb luck into smart luck.
