I usually avoid classifying sections of highway as 'dead', but it's hard to disagree with the previous poster.
I-80 through Iowa and Nebraska is pretty rough going. It's a VERY long stretch without very much visual stimulation. Only places that I find worth stopping at are towns with services. I will say that the various towns and cities "lined up" along I-80 (they are few and far between at times) are by and large pleasant...Des Moines and Council Bluffs in Iowa, and Lincoln and Kearney in Nebraska to name a few.
Good luck and safe driving. Getting there is half the fun no matter where you have to drive through.
