Sure there are plenty of people out there, possibly even the majority, who don't care a bit about the details, just the result (and many who don't even care about that). However, there's still plenty of people who are intensely interested, such as the Pakistani government, or AQ for example...
And you can bet that virtually every intelligence agency and terrorist organisation on the planet will be doing whatever they can to find out as much detail as they can - information is power after all.

There's no doubt that much of the detail should remain secret, but the information which has been produced by the US is at best confusing, and at worst possibly a complete fabrication. When certain details are released, then retracted and replaced with other details, it creates a fertile breeding ground for conspiracy theories. We don't know what is true and what is just misdirection, or even if there was any attempt at misdirection. Without believable independant sources, we're left with very little to base opinions on.

More than anything I believe it's the PR campaign which has failed here, not the actual operation itself. It seems the US were not ready for the loss of an aircraft or the failure of the mission - the PR people had it seems planned only for complete success and were caught short when things didn't quite turn out as expected. Even the possibility of the death of UBL doesn't seem to have received much forethought.
