Due to copyright
restrictions, most full length TV shows and movies are removed from
YouTube. To get around this, people sometimes post full length movies
by breaking them down into smaller parts, so you find them as “[Movie
Name] part 1/5” etc. The problem with this is if one of the parts
is missing it is incredibly frustrating to find this out half way
through the movie!
There is an official
YouTube movie channel which you can find at www.youtube.com/movies
which has lots of movies in full (and also good quality). Some of
them you have to pay for, but there are also thousands you can watch
for free. Naturally the free ones are not so well known, but there
are definitely some in there that are worth watching.
The channel also
links to www.popcornflix.com
which also has a bunch of films you can watch for free, legally. In
addition to this, I would also recommend paid sites such as Netflix,
which usually offer a months free trial, which you can cancel
straight away, no questions asked, providing you have a credit card.
