Blu-ray Series: Why not start from the beginning ?

[KenO]

Smallville
I watched the early seasons of Smallville when they first aired and have watched many episodes multiple times in reruns. I have lost track of what has been happening in the recent couple seasons and there haven't been too many reruns for me to catch up on. When I watched season 6 on Blu-ray, about 1/2 of the episodes were new to me so i didn't feel too bad shelling out the big bucks for the latest season. (If the Warner execs are reading this, I would buy season 5 too.)

Rescue Me
I bought the first 2 seasons of Rescue Me on DVD when they were dirt cheap and it was the first time I saw the show since I don't have cable or satellite. When season 3 came out on Blu-ray, I was happy to buy it but I wouldn't go back and replace the first 2 seasons. The expense isn't worth it since I don't really expect to rewatch the series very often at all.

Everybody Loves Raymond
I have all but season 8 of Everybody Loves Raymond on DVD (I have been holding out for Blu-ray). I have watched them 3 or 4 times since purchasing them earlier this year and would replace all with Blu-ray because I expect to continue watching them over and over.
