Bram Ruiter’s review published on Letterboxd :
PlayStation 3-era CGI submarines lacking any sense of scale or weight. A scruffy-looking Gary Oldman in a general’s outfit two sizes too big. Submarine interiors played out with the utmost sincerity and conviction. Everyone tries their best. Except the editor. Every proper frame cuts away to one that’s is a lot worse, as if it’s a compulsion.
This thing is a mess and I was just sleepy enough to fully enjoy it.
