He is a very perceptive philosopher, critic; his forte is that he manages to bring everything in, combining 'high' and 'low' culture, distant topics, and so on. He speaks, almost exclusively, about the 'present day', and I would say that although he is very much ideology-driven (at least he's honest about it), his analysis is often topnotch, at least in my perspective. Film, literature, music, toilets, pornography, he talks about everything, which is why, perhaps, he's written many books and articles, and has many videos scattered on the internet. I think this short video here, as it is animated, is a good introduction to some of his preoccupations.
The one analysis of his that concerns me most is for the future: that we should cut ourselves off from nature, since nature is chaotic, that we should embrace ourselves, our humanity but not in the old Genesis way of Man being the master of all things. He's also very important with regard to literary criticism. What's more, you can quote him on almost whichever topic you like, so he's very useful for university students!
