well i have ONE episode left on s3 ... and man I LOVE THIS SHOW! I can't watch less than 3 eps at one time. i am going to finish it tomrrow night. i hav access to season 1 and 2 as well, so i'm going to watch them afterwards. im sure there is stuff already revealed to me which would have been cooler to see myself in the first two seasons, although i knew his wife was killed from just watching episodes here and there on TV a while back.
this show seriously rocks. i am hooked! so is my GF which is even better so she doesn't mind watching 4-5 eps in a row!
