Can "No Country" be Upset for Best Picture?

As we come closer to this year's Oscar awards show, there are so many question marks that this may be the most exciting Oscar show in history. However most believe the Best Picture category is not one of these, that "No Country for Old Men" is a lock to win and there are really no threats to take it down. While I believe "No Country" is the best film of the year, I definitely do not believe it is a lock to win by any means.
Out of the other four nominees I believe everyone one of them has a chance to upset come Oscar night, but some have a better chance than others. The most likely upset is "There Will Be Blood" which is the only other film with many wins in the Best Picture category throughout the precursor's and it also seems to have the most momentum right now. This could be a "Crash" situation where "No Country" could have peaked too early and "Blood" is the hot film at the moment and steals a victory. Next, is "Atonement" which has extreme backing from select critics and that could help it take away the gold. "Atonement" was considered the front-runner earlier in the year but faded as it seemed like more Europeans loved it than Americans did. However, it did get nominated which shows there is defintely some love for this film out there, and it also beat "No Country" for Best Picture in the Golden Globes. This film could have more support than we realized and take a surprise win home Oscar night.
While I believe those are the most likely upsets "Michael Clayton" and "Juno" also have there chance to shock some people. "Michael Clayton" is the smartest and classiest film nominated and the Academy loves this type of film. This intricate and detailed masterpiece has been doing the most advertising for the Oscars than the other films. With commercials and banners all over the place as well as a re-releasing of the film, the film is certainly doing everything it can to win the prize. "Juno" really isn't a deep enough film to win Best Picture and I believe the backlash of critics and film connoisseurs would be rather harsh if it were to win. However, Juno has a following that really, really loves this film and it will get some votes to win; no doubt about it.
So while I believe it would be a shame if "No Country for Old Men" does not win come Oscar night as it is truly the best film of the year, it's the boring choice, the one that always wins and people get tired of seeing the same thing repeated. But the Oscar is the ultimate and the one award everyone cares about, and while it would be fun if another film takes home the award, "No Country" deserves it the most and most likely will win it in the end.
