Bad example: http://www.brillpublications.com/
Good example: Http://www.mtv.com
Brill Publications is horrible and bland, and the focus of the flash is out of place. There is a video that plays in the begining and you hardly notice it because of everything else that is going on in the website.
The MTV website I feel was an excellent use of flash because the site itself is very loud, and the flash banner streamlines the viewers attention to what is most important, which is the breaking news, etc.
