While the "daughter" subplot may not be the best choice, the show needed some emotional gravitas as it entered the second half. Almost every sitcom has good character development or emotional drama happening on which to build the humor. Back to You was feeling too lightweight entering its second half; there was no depth to the host of snarky characters. The daughter thing brings in a serious note to round out the show and characters.
That's why I liked it.
