There is still a Blockbuster open near my place here in central FL. I really like jumping on my bicycle for the short ride to it which gets me some exercise. I like browsing the isles, looking at the case covers to see what's out. They also have a huge video game section with multiple copies so I can almost always find the game I want on the shelf. The staff has always been very cool and I enjoy their conversation. They have recently reduced their prices and my favorite now is .49 movies on Sunday.
For me personally, its a welcome diversion to step away from my computer and make a trip to my local Blockbuster. I think it would suck if I had to get everything without leaving the house or interacting with the outside world.
