The amount of the original work used is a very important aspect of fair use. If I write a movie review of The Matrix and include a screenshot of Neo dodging bullets, that's your typical fair use. The reason for this is obvious, the screenshot is there for review purposes, maybe to show off the thematic feel of the movie in my review. But if I do a YouTube video review of The Matrix and then include the entirely of movie, it's not fair use. I could maybe show a scene or two, but I can't just wholesale copy paste the movie and call it fair use. After all, if that was okay, you could "legally pirate" anything by just having a 5 second review before the movie.
