Sample Reviews:
Alison Foreman, IndieWire C+ – “Iron Lung” is audacious and at times astonishingly boring. Still, it feels more enthusiastic and celebratory than many blockbuster adaptations built on safer math.
SYNOPSIS:
Set in a post-apocalyptic future where an event known as "The Quiet Rapture" caused all known stars and habitable planets in the universe to disappear, a convict is sent to search an ocean of blood discovered on a desolate moon, using a small submarine nicknamed the "Iron Lung".
An ocean of blood. The only hope left after The Quiet Rapture. In the rusting halls of crumbling space stations, the last remnants of humanity craft a submarine to explore the bleeding depths… and weld one soul inside to pilot it. But hope in this void is as illusionary as the starlight. This is not an expedition.
It's an execution.

None of these reviews are trustworthy because they are all biased towards Mark just because they know who he is.
VERY long shot but with the fan rush… Can this get an A+ CinemaScore? Whatever the case, another A for horror is good to see (also Send Help could potentially get an A- so 2 in one day)
God i love slow burn horror movies I can’t wait for this
2 reviews doesn’t really cross a meaningful threshold for trust.
He’s going to get inflated scores immediately even if the movie is awful
Wild that this is 127 minutes, pretty bold for a first time director who isn’t a “real” actor and the only major on screen character
Is anyone surprised. First people seeing and rating this will be Markiplier fans so of course it’s very positive audience score
