I quit being a regular renter once DVDs came out and I could get most new movies for under $20, which sure beat the $40 average for laserdiscs. Always hated Blockbuster because of their ban on NC-17 rated movies, which was one of the main reasons a lot of movies were cut to get an R instead- hopefully with them out of the picture, studios won't be so afraid to release movies with that rating.
Forgiving that however, Blockbuster still could have changed a few things to cater to real movie fans. With stores like Tower and Borders gone, they could have stepped up their inventory of movies for sale (I NEVER buy used!) Instead they wasted store space on junk that had no business being in a video store, like as-seen-on-TV kitchen gadgets and what-not, and kept clinging to the rental model that was irrelevant to me.
Just goes to show however what goes around comes around- if they hadn't done so much to piss off people like me, they might still be in business. Instead they catered to the sheep, who left them when the next big thing came along.
