> I disagree. After going through quite a few research papers in my time, I've found the best are the ones that are direct and to the point. Many papers I've spent many hours/days trying to unravel just to realize the concepts were straightforward, not very novel, and there wasn't much of real substance to the paper.

Can say the same thing about code. Some people just honestly don't want to give away how simple the core logic is seemingly, and will lead you through myriad twists and turns to finally see the point.
