I mean, its supposed to be Slice Of Life. And miscarriages are common, particularly in older women. Doing an episode about a miscarriage isn't any more weird than an episode about the death of a grandparent or a parent losing their job or a sibling getting bit by a dog. I could name at least four women I know, off-hand, who have had miscarriages, in the last five years. Doing a show about it is fine.

Also, The Comic was notable because of how unexpectedly good it was within the general context of the material. CTRL+ALT+DEL was notorious for its Wall-of-Text style, juvenile humor, casual misogyny, and trivialization of cruelty. The Comic was such a radical break from all of this that it kinda slapped you in the face and said "Look! Web Comics Don't Need To Suck!"

Big Bang Theory was in the style of C+A+D. It sucked for all the same reasons. So if Young Sheldon has moved away from that slimy, cheesy, ugly entertainment, that's good aktuly.
