I can say several positive things about this movie. It is possible that people who hate the perfect couples or perfect families all over Hallmark and Lifetime will like this family. I am reminded of a TV movie about "The Partridge Family" where Danny Bonaduce's father was so happy about writing for a show called "All in the Family" where everyone hates each other. The truth is there was love there if you were patient, and that's true of this family too. When Steph first arrives, everyone is happy to see her, and there are a few scenes where they get along. And I think people looking for a nice holiday will eventually be rewarded.
But this much arguing, especially at Christmas, is hard to take. Also, even though I don't like dogs, how exactly is it funny that the dog dies? Or does it? There is a lot of deception going on. And I misunderstood some of it and thought the vet was doing something inexcusable, something that would get her in a lot of trouble. I assume Australia has ethics rules for professionals. I did at least find the vet pleasant.
I did like the pretty holiday clothes. If you hate matching pajamas ... well, it wasn't like that at all.
Okay, I did like Randy, Steph's brother. And his friend Leon, who wasn't used to holiday celebrations. He tried to put up with it all.
Steph had a cousin who usually wore brightly colored exercise wear that showed off a very fit body.
The only thing I can suggest is that you either have patience or record it and fast forward to the end.
