Iron Lung
My thoughts on iron lung is that i am confuse through the whole plot— like the eureka moment of me getting it is flowing through and past my fingers as I seem that I couldn't grasp it, the start was slow-ish but not really, it threw you right in but because I have no prior knowledge of what iron lung is about it does make it seems like it's slow because it took me a while to undersrand where we're at and what is happening.
