Last ones I watched were Phantom Menace and Clones, both in the last couple of months.
But wait, wait, wait! I have a valid excuse, I swear!

Other than those, though, I'm all Star Wars-ed out for the time being, I think. Probably won't watch any of them again unless I can catch them in HD--or maybe even not 'til when the Blu-Ray versions (eventually) come out. . .
