Just discovered this show recently and I think I've seen enough episodes now to form an opinion.
Pros: Interesting and fresh concept in comparison to other HGTV shows. Not exactly "no demo" but the concept is a good one. Hostess/ designer is charming, witty, and fun-loving which makes the show fun. Most of the final designs are nice even if they show the designer's limited range.
Cons: The designs are often not practical. Lots of white walls, kitchens, and furniture when clients have small kids. She always leans towards taking out bath tubs as if no one takes baths. And when they ask her to keep the tubs, she always does stand-alone tubs with no storage. Also, her designs lack range in terms of diversity. I've never seen her install cabinets that weren't white (with a different color island). She tends to use the same greenish color for bedroom walls. I think she needs to stretch more, dare to change styles. Every countertop and cabinet doesn't have to be white.
Also, I think they could cut out the parts of the host doing things at her own home. It feels like unnecessary filler and makes the show a little too silly and unserious.
The show overall is definitely watchable and has potential to grow. Maybe the designs will get better as the young host gains more experience.
