"WHAT??!!"
The second time I heard them say "WHAT??!!" to newly-found problems, I knew the whole thing was a load of crap. No one who invests that much that many times would be that surprised that many times.
These UNreality TV shows are really wearing thin... the fix-it shows especially. They're all fake, including the almighty "Fixer Upper."
Now that the off-screen break-up has occurred, I wouldn't watch this show even if I were a regular viewer now. Few watch these shows for the work. They watch them because of the people do the work. The show is doomed.
