Curious Caterer: Grilling Season

I don't know why you adapt an author's book and then make so many changes? Can writers not come up with their own stories? The actress playing Goldy doesn't resemble the character in the book at all- I don't believe Tom had an ex wife (though I may be wrong on that), Marla and Goldy were both married to Richard who is no longer the abuser he was in the novels. Also as many have pointed out, Goldy had a son not a daughter- no need to change that- and where is Julian?! He not Marla assisted Goldy on her catering gigs. I watched until the discovery of the murder and then I was out. I won't be tuning in to any others in this series. Too many deviations from the books with none being improvements. Ugh.
