Query: starts well and goes downhill from there

John Hannah and rest of cast struggle with a common problem...writers who start like an Olympic sprinter and end totally unravelled barely able to get across the finish line. Too much silly business of McCallum acting like a 12 yr old and then audience expected to believe he is a crack intellect full of perception...without sense enough to keep his pants zipped...people are just written out of the series and others grabbed to fill the void..the last show it would seem we are to believe McCallum in living the good life in LA...no other explanation and a new head pathologist and VERY irritating and unprofessional assistant...if they weren't going to meet Hannah's salary just end the program...which is what must have happenned....UNRAVELING and whimpering to an end...too bad...it was a good premise
