A strong player (National Master) who's been giving me pointers tells me that when a strong player plays a weak player, it is almost thematic to see them drag the weaker player to the endgame ... kicking and screaming as this post seems to indicate. This is even more common when a titled player plays one of those children-prodigies who put Rybka/Fritz to shame tactically.
There's even a little saying he uses - "Take the little children to the endgame ..."
You might want to ask yourself why this is the case.
I have to side with the endgame loving folks. Most endgames are much more complicated than they look. A rook and a few pawns for each side, possibly a bishop or two thrown in, and you've got the recipe for some very demanding play. If having fewer pieces looks like a simple position then be prepared to lose.
