Seems based on this thread Netflix made the right call.
Even if someone had a Netflix membership and decided "I just have to see 'x' now" they might go to Blockbuster and drop $4 on the new release how often? Once? Maybe twice a year, by then they've spent the cost of a monthly membership to Netflix and only seen two movies.
It really is logical and an easy compromise to wait another 28 days. I'll not even notice it and apparently neither will any of us based on our comments here.
