Movie and show piracy is a very easy thing to do, like ebook piracy, most sites that host shows and movies are ran entirely on browser with no download required. Once again, there are situations where you can torrent movies and shows however we will not be discussing torrents here since I want this to remain relatively simplistic.
These sites are all helpful to find the vast majority of media you need. These sites are also extremely intuitive and should not need much explaining. Make sure to always use an adblocker, i recommend Adblock Plus and uBlock Origin (my personal favourite), both of these extenstions can be found on the extenstion store for both google and firefox and any browser that ports them like Opera GX.
