No I am afraid not. It is Illegal to have it in your possession. Sense you are watching it online then that isn't having it in your possession.
Now if it is Illegal to watch a movie that isn't in your possession then we could not go to our friends house to watch a movie.
You have to use commonsense here.
They mostly do not want for people to sale them.
And you have to know they want the big Fish not the little fish. If you understand what I mean.
But to say it is illegal to watch a movie that you didn't get legally is like saying we could not go to a friends house and watch it.
