Late to Season 2, and have a couple episodes to go, so not reading upthread for spoilers.
The comment about the storylines seeming contrived isn't unfair. It is schmaltzy at times, and has a bit of a Ted Lasso feel where there's some sort of positive life lesson in each episode. But it still does a great job at hitting the emotions, and the performances and comedic timing of the actors are excellent. I really don't mind watching a show where all the characters are likeable in some way, everyone finds redemption along the way, and there are mostly happy endings. I get my fill of dark shit (e.g., looking forward to Season 3 of White Lotus, where most of the characters are pretty shitty and there are no real happy endings).
And this may be bold, but I think Shrinking is one of Harrison Ford's best acting performances ever. I've always been a fan, but he has for the most part played some form of a hero with not a wide acting range (with some exceptions, of course, like the unexpected villain in What Lies Beneath). And while his action characters like Indian Jones and Han Solo deliver some deadpan funny lines, he's never really ventured much in the comedy realm as far as I can remember. But he's nailing this role without being over the top, and it hasn't gotten tired. If this is his swan song, it's a perfect one.
