This film is, as you've already known by now, a "trippy adaptation" of Tagore's play. Though I've never read or seen Tagore's play, I'm sure that it retained the original sprit of his work despite such hurling of experiementalism.
The film intertwines a tale and reality together, which is a surreal experience giving off a lingering desire to "know more" about the protagonist.
The adaptation of the play part particularly is not just a remake of the original one but in itself an original creation with several other ideas fused in. The way paints 'the cards' as fascist is comedically stern, trying hard to maintain the weak binding of tyranny.
I'm not dissapointed with the sexual innuendos in the film. Though I don't think it is a vital part, but at the same time it is.
In essenece the film questions "the dogma", "the dogma" which is spoonfed to us, showing us that if we begin to question our beliefs, it leads to nothing therefore it is all futile. The nihilism is beautifully potrayed.
