No one questioned how well the show was made moron. You need to find yourself some sort of a life before you end up killing your family or committing suicide.
Bert, the person who wrote the first post said that the writers and producers "really blew it" which, in my interpretation, is saying that the show was not well-made. And what is the point of posting here or even coming to this website if you don't like the show?
Criticizing a murder mystery because its portrayal of detective work is unrealistic is like criticizing "Jack and the Beanstalk" because of its unrealistic portrayal of gardening.
