Query: Why call it Christie?

I was very disappointed in this series because I was expecting Christie's Miss Marple and found something completely different that I didn't like half as much. If the producers of this series want to write their own stories and have a different type of detective, why not just do so? Trading on the Christie name and the Miss Marple character is really a cheap trick. I especially could not understand the complete rewrite of "Why Didn't They Ask Evans", which was implausible and very dark. Please don't call it Christie when it's not.
