Largely this was accomplished by not overly focusing on Malin Akerman as the new mom. She's just not interesting enough to carry a show, and if someone could get that memo to whoever decided her voice-overs would be a good idea, that would be great.
I enjoyed the choice of showing the cacophany that a multiple-marriage home would be like. That dynamic was by far the best choice made so far (other than having Bradley Whitford's character be a lawyer, which means I get to pretend he's Josh Lyman post White House). Is the choice on the larger interplay of characters a direct rip-off of Modern Family? Of course. Will it match in levels of brilliance and humor? Oh, most definitely not. But they've succeeded in not pissing me off so far, so I say go for it.
I would rather that Warren get as little screen time as possible, for my personal comfort. There's funny awkward, there's relateable awkward, and then there's oh-just-send-him-to-boarding-school awfulness pretending to be lovable awkward. No bueno.
More than anything, I like that Bradley Whitford's character had his own separate parenting story, it made it much more interesting than just seeing Malin fail at making roadways. Besides, the exploding hamster and the hide-a-key plot were by far the best parts of the episode, they were the two moments when I laughed out loud. Once again, this just supports my idea that this same show with the focus on the husband would be just so much better.
But before I go, there is one more important question I have to ask: Karaoke is cool? Specifically, karaoke is a cool thing that sexy single city ladies do? I'm not denying that karaoke fantastic, but I always thought it was like bowling, where it's a great time but actually completely rejects any attempt to make it cool.
