But it’s also not images for the sake of images. It’s a pretty linear Western (the so-called predecessor to acid westerns) but instead of being a morality tale - a lone hero trying to tame the wild west - it’s more of a spirituality adventure, a lone hero trying to attain enlightenment. In the literal sense, he has a family he trades for passion, and he wants to be the best gunslinger in the land to impress his new damsel. But the four best marksmen in the land actually represent four different philosophies, so when he kills them in succession, it’s really him outsmarting their different beliefs - he kills them by being more cunning.
In searching for enlightenment, he forgoes passion, family, and the four prevalent religions of his day.
And in the end, it’s not good enough. His quest was based on ego - he wanted to outsmart them, not learn and understand their beliefs. And so he is “killed”, but really he meditates for a long time on what they told him and resurrects as a Christ-like figure in a cave of human suffering, which he vows to end.
And he tries, but it doesn’t work. But more importantly he is killed in the act of saving others, which is to say he’s finally lost his ego, finally reached a state of enlightenment. We also know he reached enlightenment because the four marksmen he had slain earlier - men who had reached enlightenment in their own philosophies - had their graves covered in bees, the same as the lone gunslinger at the end of the film.
Now, can you find any more meaning in the film then that? A little, but not too much. It’s definitely a soup of different religions (especially eastern ones, Buddhism especially - enlightenment is only possible by divorcing yourself from ego, etc) but I don’t think exactness was the point. It’d be a boring, pedestrian film if the four different marksmen were exact metaphors for different religions, or if anything was spelled out much more.
Really the film is about the quest to find meaning, a quest that’s behind so much of human history and lore and art and culture. But that quest is so prevalent and so universal that to deal with it in a direct, head-on way would be boring and lifeless. If it was the gunslinger reenacting Buddha’s quest exactly, it’d be interesting but have no lasting power, it’d be just another religious tale.
Whatever power and intrigue lies in El Topo is because Jadorowsky tries to abstract that quest, generalize it, and make it into a watchable “action” film. The fact that you can read it as a Buddhist, Christian, Islamic, or Taoist allegory is not an easy thing at all to accomplish with a film.
And I do agree it’s pretty unintelligible at times, and seems random for the sake of random. I don’t at all believe that there’s exact hidden truths behind every symbol used, etc. But not all the symbols are random - like the bees on graves, for instance - and not all of it is a meaningless mess. There’s definitely a story in El Topo, but whether you find it interesting or not just depends on what you expect from it.
And no, I don’t think making a western where the protagonist searches for enlightenment rather then law and order is pretentious, nor do I think it’s deep just because. It’s a choice, and a perfectly valid one, and at least something different then all the Westerns that were being produced at the time. YMMV.
