VERY hit or miss. It has such an incredible cast, and a terrific concept, that it's amazing how bad they're able to make the show sometimes.
As an example, Jen being sickened by Greg's "s" sounds is a hilarious concept and a fun riff on both real life pregnancy and typical sitcom pregnancy stories. They could have done an entire 4-5 minute segment on just that, and also sprinkled it throughout the rest of the episode. (It could have culminated in him trying to learn sign language but she still runs to the toilet when he signs an "S".) Instead, she's also sickened by everything else he does, which removes the focus from the actual funny part and turns it into something annoying.
The first and last segments (Tyler's demo, meeting with the pregnant girl) were both okay but they had no substantial comedy value. Tim's story - "I've never told you this about me", "Diving?" - was good, but it fell into this show's other trap. Funny setups end in played out, predictable stories. Wouldn't it be funnier and unexpected if he WAS an incredible diver?
Was there any question that the girl would pick Matt and Colleen because their cheesy Minions picture?
Was there any question that James Brolin's character (haven't bothered learning his name) would pawn the work off on his children?
Plus... wouldn't it be funnier if it turned out that after 50 years he discovered he actually was good at all those things and enjoyed doing them? That would be a more unexpected turn of events with so much more room for comedy. If you wanted to return the the status quo at the end of the episode, have the grandmother discover that she likes taking care of him and is jealous, so Brolin lies to her and tells her that the kids were doing all the work. (Which leaves it open for later, he could be caught cooking when she's not around, or holding secret dinner parties, or going behind her as she cleans the house to find spots that she misses.)
I don't normally question shows this much or write my own better versions because it's a fruitless endeavour, but I loved this show so much from the start and now it's a huge glob of wasted potential.
