I think there must be some legal issues around making video essays. Like so many people now are making them and uploading them on youtube. Maybe famous people on youtube should have legal licenses or some kind of permission about their enterprise, but not-so-famous ones may not but are ignored because of the large number of people who do this. It depends on how much youtube or any other video uploading webpage restricts those who have no licenses and are considered as illegal activity technically. In my opinion of respecting films, they should have certain allowance to use and clip films in any ways. I like the idea of video essays though, which can make people who are not interested in movies become into movies.:)
The function of an argumentative essay is to show that your assertion (opinion, theory, hypothesis) about some phenomenon or phenomena is correct or more truthful than others'. The art of argumentation is not an easy skill to acquire. Many people might think that if one simply has an opinion, one can argue it successfully, and these folks are always surprised when others don't agree with them because their logic seems so correct. Argumentative writing is the act of forming reasons, making inductions, drawing conclusions, and applying them to the case in discussion; the operation of inferring propositions, not known or admitted as true, from facts or principles known, admitted, or proved to be true. It clearly explains the process of your reasoning from the known or assumed to the unknown. Without doing this you do not have an argument, you have only an assertion, an essay that is just your unsubstantiated opinion.
