The original post argued that Drinking Out of Cups is an experimental film. I disagree with this categorization. The original argument is that because Drinking Out of Cups has no narrative than it is experimental. I think that this is simplification of what an experimental film is.
If Drinking Out of Cups is experimental, than what is the experiment? An experimental film is trying to do something different with structure, technique or writing. Drinking Out of Cups is certainly not something that we would normally watch in a movie theater, but it is completely within the normal elements of its context.
Drinking Out of Cups is not an experimental film, it is just a meme film. For a youtube video that is intended to be funny, plotlessness is not only not experimental, it is par for the course. I do not find Drinking Out of Cups to be particularly odd for a youtube video. This makes it unexperimental.
