I wasn't interested at all in any episodes without Methos. He was my sole reason to rewatch the episodes.
*nods* I tried to do a complete rewatch when I bought the DVDs but ended up skipping those without him :p

Speaking of Duncan being annoying: One of my favourite scenes is from "Forgive Us Our Trespasses" when Methos shoots Duncan in the back to kill him temporarily and says: "You're such a pain in the ass." LOL. So true.
