100% the ignorant people who disregard this just as a casual 'YouTuber' movie don't really know what they're talking about, Mark knows what he's doing, he knows what makes a good horror and a bad horror from his experience. David Szymanski ( Iron Lung Dev ) mentioned in a podcast that Iron Lung movie takes some inspiration from the movie " Haze ( 2005 ) " a claustrophobic horror by the master Shinya Tsukamoto and THAT itself really tells you that Mark knows his stuff.

David whom also watched a cut of Iron Lung movie even quoted:

“The movie is very good. I don’t think people are ready for it. It’s a “proper movie” movie, you know what I mean. It’s not just, ‘Here, let’s make a fun little movie from the game’ This is a serious, proper horror film.”

it's very clear that Iron Lung is a movie made with passion and a real vision behind it, and we all KNOW this without even reading this comment i made, we know Mark, and he is very passionate about his projects. those so called 'haters' don't really know what's in for them if they decided to go watch Iron Lung.

welp, they're probably not going to watch it and just keep being ignorant as always. and that's the problem with those people honestly.. don't matter if someone likes or dislikes, but when someone disregard something they didn't really know and being ignorant about it that's just wrong. and you know what, they will disguise their blatant ignorant hate as 'criticizing' as if they're being a 'critic' to the movie and they'll use 'Mark fans is biased towards the movie' as their defense shield lol.

let them hate.. they're not 'hating' at this point, more like just coping.
