A good defense beats a good offense, writ large.
Also, I only laughed at one commercial, which was the McD's spot done by the bad lipreading boys. That may also have been before the game started.
Don't get me wrong. I enjoyed watching the game, but more as a case study than a sporting spectacle. The Seahawks were on to everything the Broncos did. Awesome scouting, coaching, practice and execution.
Regarding practice and execution, see also Mars, Bruno. Finally an entertaining half-time show, that was about putting on a show and not about ego-tripping over how awesome he was because he's doing the SuperBowl half-time show. Anyone who didn't, at least, appreciate the showmanship and - for once - actual live singing, is simply trying not to like it.
