It is not illegal to watch movies for free on Putlocker or on any other online streaming platforms, according to FindLaw. After the backlash suffered by Congress over Stop Online Piracy Act, legislation to regulate the Internet on a more strict level is still pending.
It is not against the law to watch online content as long as the viewer is not downloading, reproducing or redistributing it, explains FindLaw. The person who posted the content online is the one who is responsible and may be prosecuted if the action is illegal.
The legality of the content being streamed is gauged depending on the websites being used, notes New Media Rights. Content on popular platforms such as Netflix are most likely legally uploaded, while those on platforms such as Putlocker may have been uploaded illegally.
