Is there an Oscar curse?

Is winning an Oscar a curse or a blessing? Some people think it could go either way. Many actors have gone on to achieve greater success after the fact. Clint Eastwood, Tom Hanks, Gwyneth Paltrow and Kate Winslet are a few examples. Others have won an Oscar and then went on to make movies that were not exactly up to par. Take Cuba Gooding Jr. for example he gave an amazing performance in "Jerry Maguire" and went home with an Academy Award. After Jerry Maguire he went on to make "Snow Dogs?" All I am saying is it could go either way. Once you win an Academy Award you automatically get pushed up to another level of celebrity. Some studio's may not approach you because they think you would decline a role or you would be to expensive to pay. It is an amazing honor and accomplishment to receive an Academy Award, but when it is all over people must wonder, what am I going to do next?
