To be honest, I almost turned it off at the very beginning of the film because it seemed like a bad joke. I read some very bad reviews and some great praises, so I decided to be open-minded about it. Obviously, it's controversial, which might be what's so fun about it.
I appreciated hearing some of the insightful thoughts presented by Seneca (John Malkovich) about the human nature, life and death etc. In this way, the film is meditative.
I enjoyed the visuals to an extent. I noticed the grotesque visual elements, which were certainly not easy on the eyes, but they had a purpose and actually went well with Nero's horrible character, as well as the absurdity and malignancy presented in the movie. There also were some "quirky" and seemingly unnecessary components.
However, in general, the characters and spaces seemed to be visually portrayed in accordance with the personalities - when you observe them, it just makes sense. Furthermore, this piece also contains elements more pleasing to the eye. I liked the recording style, the perspectives, the way scenes were organized, the colors used. That being said, the movie still definitely has a bizarre quality to it and not everyone could enjoy it.
While the piece offers some profound thoughts, it also contains plenty of frivolous elements. There were things I liked and things I disliked, as well as some choices that just didn't seem to make sense.
All things considered, I don't regret watching it. It was certainly entertaining and even thought-provoking. It's an occasionally smart movie, but it's not supposed to be taken too seriously.
