This project caught my eye because I am a big book reader and would be interested in watching videos such as this these myself. I am also a big fan of the youtube channel Cinema Sins and their videos 'Everything Wrong With',these videos critique films in a funny way.
I have some suggestions for what you could film for the book critiques: a video of the books you read in 2018, reviewing them and ranking them in the order of your favourites. You could also film another video on the books you intend to read this year. Another video idea is to film a video on the best book you've ever read, similarly the worst book you've ever read. A video on the book you are about to release, talking about the inspiration behind, when it comes etc, would be a great idea.
For the movie critiques you could film these one of two ways; you could either do it in a funny sarcastic way making light of things that don't make sense to you in the film in the style of Everything Wrong With or you could do it in a serious style and talk about how the film fits into society for example and how the film will do during the awards season.
I would be interested to know what social issues you have in mind to make a video for. I would also be interested in knowing what you current Youtube channel is called so I can get a feel for the videos you have already produced. Ultitmaley this is a proposal without seeing the intended footage but I would be happy to edit any content you produce for your channel.
