A 90-minute movie with a decent image quality doesn't necessarily need to take up 14 GB. The proof can be found in YTS YIFY, the web that provides us with movie torrents in HD, guaranteeing the minimum space required for such purpose.
A great collection of movies in HD
It's a website full of torrents where we can find movies ripped in the highest quality. We only have to browse through its catalog or use its advanced search tool to find what we're looking for. Once we've got it, we simply have to access the datasheet and click on the green Download button to choose the download option that suits our needs the best. We're talking about movies in their original language but you won't have any trouble finding subtitles adapted to YIFI's ripped films.
Apart from that, you'll probably miss some sort of organization by categories to be able to explore the database and access all the contents without resorting to the search engine. However, you definitely won't have a chance to miss any adverts... There are plenty of them all over the place.
