I've always thought of the Summer as TV's dead period, but in recent years, it seems like there are so many great shows to get us through the lull. True Blood is the obvious example, but basic cable series like my new obsession Pretty Little Liars have also been occupying my DVR. As if that's not enough, it's also a great time to catch up on older TV shows that I've been meaning to finally see. (I've got one friend who's finally getting into Freaks and Geeks.) So, as we wait for the debut of the new Fall TV series — and our favorite returning ones, of course — tell me, which shows are helping you pass the time?
