There is a precedent for this kind of character (consider Kevin J. O’Connor’s role as the plucky sidekick in Deep Rising ), but Underwater is not a tongue-in-cheek film.
Underwater harkens back to such movies as Alien, The Abyss and Deep Rising, and it made me think fondly back to those titles.
On a scale of The Rift to DeepStar Six to Leviathan to The Abyss , I’d say Underwater is more like an Alien -infused Deep Rising more than it is anything else.
Yet the intermittent sequences of alien-like interference plague the otherwise sensible scares (and the abundance of swift jump scares); nothing works against the engaging costume designs, the low visibility and flashing warning lights, and the menace of looming death like unconvincing monsters (wandering down the path of films like “Leviathan,” “Deep Rising,” and “DeepStar Six”).
