Eh, I like it sometimes. Renting a movie digitally costs $5+, renting that same movie from Redbox costs ~$2 and I don't need to give up my info to some online service. it's a little annoying going there physically, but I also have the option of ripping it from the DVD and watching it later (legality may vary, YMMV).

So online rentals are more expensive and less privacy-friendly. That's enough for me to favor Redbox.
