Show has potential. Not sure if it will be seen.
I personally hope NBC brings the show back. However the writing needs to find a good pace to developing the characters. I enjoyed how Tracy was pointed out to have qualities of a bully. If you look over several episodes you can see this.
The fact that Angie is pregnant and it seems she is happy and Russell is happy as well is a little far fetched. They are written as a couple who don't want children and have shown that sentiment throughout the show. Only one show, with Russell dog watching, gave any inclination that he and Angie might have second thoughts. A little too soon for her being pregnant. A second season would have been a better place to have her pregnant as a season ending episode after more development of that storyline.
I hope we'll see more character growth and growth with the writing if the show continues. If it doesn't return I can see why although I think the decision to pull the plug will have been to early.
