It's not a website but Popcorn time is the best program if you want to watch movies in full hd without skipping. It has a database full of movies and tv shows and if the movie/tv show you like is not in the database you can just download the .torrent file and use popcorn time to stream it
Just be aware when you click a movie, you must likely will get a pop-up. But, it always works around 90% of the time for me. They got every movie I could think of lol
