All I want is for any TV or movie on iTunes that is purchasable to also be rentable. I don't have any desire to buy, say, The Social Network for $20, but I'll rent it for $5. This goes double for TV shows. I love Fringe, but if I miss an episode I don't want to spend $3 to buy it, watch it once and never see it again. Let me rent it for $1 and I'll be happy.
