My favorite site is called "fanserials", it has a lot of my favorite TV shows, and other interesting things.
On this site, good video and voice quality images from different languages ​​to Russian, to choose from. This site has a dark colour that is pleasing to the eyes and for watching serials in the dark. Also on this site you can leave a review about the video, or read someone's opinion about what they saw. Also on this site there is a newsletter about serials that you do not want to miss. The main disadvantage of most sites is advertising, which also present on "fanserials".
There are many sites for watching serials that are similar to "fanserials", but I like this site.
