But there's also the situation where a team dominates a game, the other team scores a couple TDs in garbage time and the game seems a lot less impressive.

One I vaguely remember involves a Big 10 team that thoroughly dominated the other team and had a 35-7 lead very late. The opponent scores a few late TDs and 2 pointer, then scores again on the last play of the game to make it 35-29. Looks like a close game to a computer just processing the score (or to a pollster just looking at the final score).
