Long, exasperated sigh. I remember watching this a while back and thinking, "selfish? who does this guy think he is?" I'm likening this to the stereotypical inexperienced unrelatable anime protagonist with a twisted opinion on most things, but who would ever have this opinion, really? "Having children is selfish and inconsiderate to people who don't exist, so let's just all be selfless and die out as a species." Shrinks would be lining up for a chance to take this guy's money. This is the kind of thinking that, if acted upon, would get you institutionalized.
I'm about to watch #2, so I'll reserve all the stuff I could have said before it came out for consideration while I watch it. I like the idea, but Calvin's personal opinion on procreation just really brought it down for me, despite how stupid--excuse me, "unpopular"--it's supposed to be(she was obviously asking if he would like to have children someday, not his opinion of living things procreating in general). I'm not bashing you, after all the character said it, not you, and it would be a big leap to just assume that this was autobiographical.
