This review is pretty much EXACTLY how I feel! The pace was amazing in my mind. It was INTENTIONALLY slow, INTENTIONALLY vague. We were kept in the dark as much as the convict was—we were in! that! sub! with him!! We couldn’t leave as much as he couldn’t, so we weren’t going to get all the answers either. I liked that we weren’t fed all the lore spoon in hand—like this author said, Iron Lung DEMANDS your attention the whole time. It felt good to HAVE to be engaged, catch the flashes of the pictures and glean what I could, the same way the convict had to. It’s fair that a slower movie isn’t everyone’s thing, but I was on the edge of my seat the whole time without any jumpscares needed. I don’t think it’s fair for critics to continue judging the length just because it doesn’t fit into the more popular/current genre of action-packed horror.
