Watching movies online used to be quite the ordeal. Either your computer got infected with dozens of trojans or viruses, or the movies looked like they were shot underwater.
VeeHD.com goes to show you that things have gotten a heck of a lot better since then.
Although they don't have many newer releases, they have a lot of popular films available to stream in spectacular high definition.
Just click on any of the movies listed on the page, and you'll be directed to a page with the HD video. Best thing is that the website doesn't have any ads! I don't know how they make their money, but it sure is nice.
