It's very painful, but I have the ability to experience something painful and then just compartmentalize it away as I enjoy the rest of it. Believe me, The Breaking Point in particular had me in tears on my rewatch, but I still manage to package that pain away and enjoy the rest. I think it helps that they chose (purposefully, obviously) to focus the most on the men who made it through the whole war - in this spam I think only 2 die, though more are wounded. So I'm okay with getting emotionally attached to them. IDK. I do understand where you're coming from though.
