The film’s slow burn wouldn’t feel so staggering if it built to something wholly worthwhile. The blood, hallucinations, and sea creature are all great, but they’re too fleeting to make a lasting impact. Iron Lung promises something grand and cosmic, but its climactic reveal is abrupt, with few scares and only a brief glimpse of the monster. Ultimately, it’s two hours of tension that end in a bloody yet unsatisfying climax. https://bit.ly/lungofiron

If anyone were to ask me if they should watch it, my answer is definitely more direct than the supposed "answer" in the mov…

Interesting but somewhat incoherent Adapting games to movies is hard, and this movie does this better than most. However, the game being adapted is a peculiar one, and it lends its air of peculiarity to the movie as well. It is a tight and spooky premise, and I am sure that if you have played the game you will get more out of it than someone who has not, but it becomes strangely rambling at times, possibly because the underlying narrative is so dense that the adaptation could not quite pierce i…
