Hunter Killer, based off the 2012 novel "Firing Point" by Don Keith and George Wallace, is a decent enough film, with flaws showing from its adaption from a 600 page book (Red October is a little less then 400 pages) that still manages, despite flaws, to be an entertaining film that lets civilian catch a glimpse of the world inside an U.S. Navy attack submarine.
If i had to pick the films two biggest issues, its poor effects at times (The use of stock footage at one point was jarring) and the "actionazation" of some scenes (A sniper kills upwards of six men, all with head shots, and not one of them takes cover or tries to suppress him as their fellow troops fall like nine-pins)
The film does have some merits too, some of the tactics in the film are accurate (A perk of U.S. Navy co-operation on the film) and the sets are film* accurate to the real life Virginia class sub the film is portraying, thus building atmosphere for a major setting of the film.
*They of course, have left some things out for reasons of secrecy
In the end,Hunter Killer is a film that fails to deliver a story equal of it's source material, but succeeds in at least giving the audience a thrilling ride bellow the waves into enemy waters, and all us Sub Buffs get to cream our pants with the cry of "Torpedo in the Water"! echoes through the theaters once again.
