I don't know if they were filming a real house or what, but it was very, very dirty. The walls all looked like someone had been sitting there smoking for 20 years. In subsequent episodes, it appears, they painted the kitchen cabinets and everything looks cleaner.
Also, there were some continuity errors. In episode 1, Nancy is pregnant. We never hear what happened with that, but she obviouslystill only had Timmy.When Kate complains that she wanted to abort all three of her kids, she neglects to mention that she actually had four children but one died we find out several episodes later.
