I haven't started this season yet. As we have been have discussions about different things this year and people were asking for recommendations for good series to watch I said two or three times that there are so many good "older" series which I would gladly go back and watch and drop all current stuff. I ploughed through Buffy over summer, I started watching SG1 by accident last month and couldn't stop so I am half way through that I have just started watching Smallville. I have seen SG1 many many times but I have never gone back and rewatched Smallville from the start since it finished. Seeing Lana is like falling in love all over again
Long story short is that I am way behind on all current series atm because imho I am watching better series. When I have finished Smallville I want to do BSG.
