They don't seem real, welcoming or believable
I don't know if it's their California personalities, or what, but I despise these two. She looks fake, plastic and straight out of a toy box from the little girls' toy aisle. He's obnoxious, arrogant and annoying. I just have a hard time believing them and they seemed so scripted.
I no longer watch this show. Go look at Fixer Upper's ratings on IMDB compared to Flip or Flop. That says something.
I prefer Chip and Joanna Gaines on Fixer Upper. Those two are real people and it shows through on their show. Perhaps Flip or Flop should take notes from Chip and Joanna on how to be a real couple and get people to like you.
