Yeah, his movie analyses are usually done through the lens of psychoanalysis akin to Freud/Jung. Which is great if that's your thing, but isn't great if it's not haha.
I actually just read how to read lacan a few weeks ago who's a major influence in his work. Infact I'd go so far as to say zizek gave lacan the relevance he never had by reworking many of his ideas.
Jizzmaster you have to watch that movie, it's one of the trippiest movie i've ever seen. And it's particularly charming with subs instead of the dubbed version.
