How do I download a ton of movies using RealDebrid?

I am very noob to Real Debrid. I got my nose into streaming with KODI on my PC and using Cinema for my FireStickTV and I love it. But I really want to download a lot of Movies to my PC and export them on a SSD, just to have them for my travels.

What is the easiest way that I can just download the entire pirates of Caribbean movies, harry potter or game of thrones for example using RB?

Thanks for you guys expertise and knowledge. I hope one day I'll be as good as you guys using RB! Thanks!
