I liked this a lot. I think a lot of the criticism/tepid reviews are based more on people being disappointed that it isn't what they hoped it would be, rather than judging it on what it actually is, if that makes sense.
I just feel like even moreso than Glenn Close, poor Amy Adams' lack of an Oscar win has turned into this SAD SHADOW that hangs over everything she does now.

If she'd already won one for something before now, I suspect this would be warmly received as a quirky, low-stakes cinematic tone-poem about motherhood and femininity, but instead it's doomed to be viewed by many through the lens of "IS THIS THE ONE? Oh dear, it isn't.

"
Poor cow, it must really wind her up.
Anyway, it got plenty of chuckles (and a few winces!) out of me, the kid was very sweet and non-annoying and it was a blessedly brisk 98 minutes long, so I could forgive the fact that not much really happens and it doesn't really lean into the full-on camp that the trailer suggested.
Negatives: The CGI looked quite distractingly fakey in places (those dogs!) and the relationship with the husband all felt a bit pat, particularly the way they wrapped it up.
But on the whole, very charming and the best I've seen Adams in years and years. Probably since Arrival. Nice to see she's still got it in her after some of the dodgy stuff she's been stuck in (and frequently quite bad in!) over the past few years.
