You have valid points. I binged it in one sitting...Heres my take. They are trying to tap into the trend of A million Little Things, Or This is Us. But with an edge. I liked the series, but whats much better is "Easy" on Netflix I believe. same premise, but much more intense, and not all happy endings. Give that a try. There are 3 seasons I think, and you wont be disappointed.
Modern Love was renewed for a second season. Since I saw some pretty good acting scenes in season one, for me, its worth watching.
I did watch Easy and liked most of it, though one or two characters kind of were unrealistic in some of their behaviors (the chubby husband for one).
A couple irritants of mine when it comes to these shows are when they are so cookie-cutter cliched and when the characters do incredibly stupid things without any sort of explainable caveat for the viewer when they are supposedly hyper-intelligent (the show Workin' Moms from Canada had all sorts of the stupid acts through the show).
I am on the second ep right now and enjoying the show so far, but your post made me think of Love Actually. When I first saw it years ago I thought it was very enjoyable. Tried to rewatch it recently, and oh my god, it's so saccharine and unrealistic, a lot of it just makes you want to hurl.
