http://www.watchseries.eu is good.
I like to use XBMC to watch streaming stuff.
http://xbmc.org/download/
Then download this navi-x plugin.
http://code.google.com/p/navi-x/
Install it from the zip inside XBMC under System > Add-ons > Install from zip. Then go to Programs > Navi-x and look around at all the different sources of movies, tv shows, tv stations, etc.
Navi-X is a media portal that lets you play almost anything streaming you can find online, given someone has written a script for it (there are lots). It is pretty much like 'on-demand' cable, but more hardcore and free. I don't pay for cable tv or anything because I really just don't need it. I can even stream live tv w/ navi-x.
Within Navi-x you can watch streaming stuff from watchseries.eu, which has fast releases and tons of series and movies, but without all the ads and shitty popups it throws at you when you visit w/ a browser because people have written custom scripts for it.
XBMC+Navi-x works great on a computer, but you can also buy a $50-100 apple tv box and jailbreak it, then install XBMC on the apple tv box and connect to an HDTV via hdmi @ 1080 resolution. Then you can not only stream from web pages, but local network shares also. You can stream torrented 1080 blueray rips to a TV right off of a central server in your house.
