Agreed, and while this is the eagle's first time to the big game in a number years, the Patriots have been there many times. I say this not to gloat but rather point out that outside of New England, people may be less interested in seeing the pats play yet again. Also I wonder if the half time performers have any impact on people watching. That is, are the folks who typically watch football Justin Timberlake fans? I kind of doubt it, but who knows. Conversely, will Justin Timberlake fans watch the game because he's performing (or will they flip on the game at half time)
If the Eagles were not there, I wouldn't watch it. As you said, seeing the Pats in there over and over is anything but exciting or enticing. Also, Justin Timberlake? I'm sure there could have been someone else....
