The end of movie Web sites?

More and more I see ads for movie Web sites (especially teen and young adult targeted movies) that are hosted on MySpace. Just a couple of the latest are Step Up and John Tucker Must Die.

Considering that it’s likely cheaper to build a site on MySpace than standalone, and considering that teen movies like this are nearly certain to have limited appeal and thus limited release, I wonder if standalone sites are doomed. Heck, for that matter I wonder if non-teenie movies might end up using the same method.

What do you think? Are we seeing the end of the movie Web site?
