Not as funny and so overly sentimental. A limp sequel.
'A Bad Moms Christmas' is basically 'Daddy's Home 2' - which, interestingly, was released less than a week after this. Mila Kunis (Amy) in the lead role isn't as strong, nor are Kristen Bell (Kiki) and Kathryn Hahn (Carla) unfortunately. They have a few bits, but not enough. Christine Baranski, Cheryl Hines and Susan Sarandon are meh newcomers.
The ending particularly dragged, with it going full on preach mode and is far too cutesy. It'd be fine if it also wasn't so predictable. I noted the music in 'Bad Moms' as being good, but even that drops a level in this follow-up film.
It could've been worse, I guess, but I just didn't find entertainment with this.
