It was probably the best game I can recall in recent memory -- looking at previous Super Bowls, I see that New England has had more than its fair share of 3-point margin games, though they've usually been on the other side of things.
As to the commercials (for which MySpace was the official online partner, though AOL's page is still good) -- the best were okay -- mostly for fizzy, sweetened, or alcoholic drinks -- the worst were horrible, and the rest were bleh:
* Sales Leads Are for Closers! They could be peddling the Glengarry leads for all I know, but those horrible, horrible animated Sales Genie "100 free sales leads" commercials inexplicably employed unfunny, edge-of-racist ethnic stereotypes for no apparent reason.
And the fact that there were two of them gave me a horrifying flashback to the worst of the dotcom bubble 1.0's burn rate excesses.
* For Your Next Supercar Purchase: The Godfather parody ad for the Audi R8 was okay (though they might as well have gone the whole way and done a shot-for-shot remake) -- but it was for a US$100,000+ supercar. Yes, yes: Halo effect and all that. But come on.
* Women Loved Temple of Doom, Right? Careerbuilder chose poorly with the gruesome images of the heart jumping out, Alien-like, from the woman's chest. I felt like shouting, "Indy, cover your heart!"
* Guilty Pleasures: With shame, I have to say that I liked the Tide talking stain (the nonsense syllables put it over the edge for me), and people (I'm not saying I was one of them) did laugh at the commercial for the Adam Sandler movie. Though it's still not enough to make me want to go see an Adam Sandler movie.
* Last Words: Overheard outside a Harris Teeter after the game: "There's no difference between a foreigner and someone who just doesn't watch football."
