Astrophobia banks a little too hard on its premise. If it wasn’t for this set-up, say if they were cornered while being hunt down or running out of supplies while stranded on a mountain, the conversation here (literal and metatextual) would not be nearly as engaging. My feelings aren’t “damn, I’m sad for Nova and Albert,” but more “damn, I’d hate to be in their place,” which I’m not sure this is going for.
