Failing to notice the culprit is alcaline (if it is so) means the reviewer is completely junk.
I've no idea where you get that idea. The K-m comes with 4 Lithium AAs. The manual itself states, "We do not recommend their use except in emergencies and checking the camera functionality."
And the reviewer has stated they were lithiums:

After talking quite positively about AA batteries for what could possibly be the first time in my life, I found the power consumption too much to handle. I used four new AA Lithium batteries and they were dead in 24hrs. I didn't use the camera excessively although I did use live view, so that could be the issue.
For clarification, the batteries were from an unopened packet so I knew they'd not been used previously. From my time in retail, I know that manufacturers can use half charged batteries to give away because they're cheaper but I'd still expect a lot more from this type. I didn't use live-view constantly, but possibly used it more than a photographer would because I was testing it.
Since he doesn't seem to have used anything excessively, I wonder if it was possibly a defect in the camera or batteries. I've actually had one occasion where brand new lithiums read as depleted when I popped them in. I later checked their charge and they were dead.
