Until now I hadn´t watched CSI: Miami from start to finish. The first four seasons were really good. With the fifth something changed. Writing dropped at leats two steps. Some of the cases were not only unbelievable sometimes they seemed to have forgotten how to use their evidence. The started story arcs left, right and center only to close them down quickly because they didn´t work. Alltogether the whole show became to flashy. I might have stopped there but I wanted to know how the story around Horatio evolved. Unfortunately it didn´t really. In general the show became better towards the end but CBS cancelled about 4 weeks after the final episode of season 10. So they never got to close out the show.
As a whole it still is a good show. I don´t like the comparisons between the different CSI branches. I think you should see them all independently. And to those who are always complaining about stuff like how it is not possible to get DNA result within minutes: you´re right. But would you rather wait until next season for the conclusions ?
