Theory: The quality of anything in inversely proportional to the amount of advertising for that thing.
Proof in progress: Elizabethtown
If I could go one day without seeing an ad for this movie, I'd be happy. The first time I saw the preview I was vaguely interested in a "both of those people are attractive enough to distract me for 1.5 hours" kind of way. But after 2 weeks of constant innundation I know there is no way this movie can be good.
Also further proof this movie sucks arrived when every time I tried to close a browser window and brought my mouse too close to my IM window a big picture of Orlando Bloom and Kirsten Dunst swooning at eachother appeared. And if there is an advert for it on my IM, then I KNOW it isn't going to be good. (See Also: America's Next Top Model)
The sad thing is that advertising like this works, I am so brainwashed by this point I will probably go see this stupid movie just so I can say "THAT MOVIE SUCKED" every time I see an ad for it. (which will no doubt be ever 5 minutes for the next week at least, and then every 2 minutes when the DVD comes out in a month)
