First up, the series is fantastic with excellent story lines and plots. The quality of the Blu-ray transfer is top notch with superb sound. I agree with most fans the first 4 seasons are the finest in the series; however, as far as the final 4 seasons go they are well ahead or just as good as any of the top notch series being aired during the initial run of the series. My only 2 issues are first, that the blood slide case is not made of wood and could possibly be damaged if not kept under careful care. Second, for those who do not have BD Live, they will not be able to enjoy the extras from each season. However, there is an excellent disk filled with extra goodies which is top notch. Aside from these 2 issues, it is not enough to rate this below 4 stars as it is the series itself and the excellent transfer to Blu-ray that maintains my overall rating review. If you like Dexter, buy and enjoy.
