If your into high quality movies, then your sure to like movie6.net.
Movie6 does a great job finding videos that don't look like they were shot underwater.
On the right column of movie6, there is a list of all the movies that they currently have streaming. Just click on the link, and start watching.
The only downside to movie6 is that they don't like to link to stage6 videos (DivX). If they choose to have more DivX videos, then you wouldn't need another movie video site.
