What is the ruling on watching a leaked series for free on other websites, and is it permissible given that paying a subscription to platforms is a waste of money?

Intellectual property rights are protected and may not be infringed upon. Therefore, it is impermissible to watch copyrighted material through illegal means, even if the subscription fee for official platforms is expensive. Furthermore, series that contain forbidden elements are absolutely impermissible to watch, whether on official platforms or otherwise.
