It's a fine sitcom that doesn't reinvent the wheel or does anything particularly interesting, while some of the jokes do not land it is fun.Tim Allen and Kat Dennings and the entire cast are good and have solid chemistry together.
I do hope there is a second season, by the end of the season, the show found it's footing and had some moments full of heart, so i do think a second season would improve on the season, and maybe even improve some of jokes.
