The guy who was giving a scrum workshop at my previous job claimed that for him the thing led to
less overtime and stress, the logic there being that because they can dice up a big thing into small bits with a weighted 'cost', it was easier to set a daily quota for themselves that they could meet or exceed.
This does assume that management gives you a reasonable quota to begin with.
Which is clearly not what my countrymen were doing with RedKing's misadventure. No project management philosophy will save you from stupidity, especially not when applied in a hasty slap-dash effort only after things have already gone down the crapper.
Blaming that all on scrum seems a bit misplaced. No, stupid managers should deserve full credit for their stupid and get to sit on the cannons during test firing that they ordered to be made in half the time, from suspiciously cheap iron. But that's rarely the way things go so better wear some sturdy pants for release day

That all said I think scrum could work for smaller teams, even though all the overhead from meetings and documentation can be a pain. I don't think it should ever be used to save time, but rather save headaches on long-term projects with small-ish teams.
