Heres a few things outside the cave that can help you on the journey. What you like or dislike is quite alright and very subjective and will change as you grow visually.
Words at the bottom of the first page that I find so important.
The important point to remember is that we should all feel free to like or dislike what we will, on grounds of personal taste. HOWEVER, please note that there is a distinction between personal taste or preference and objective judgements of success or failure in a work of design or art. It is possible to recognize that a work is successful and significant, even though it does not suit our personal taste. It should be clear that unless one can lay claim to a high level of expertise it is rather immoderate to condemn a work as "bad" just because one doesn't like it. It is important for an artist to understand this distinction, and even more so for a designer, who will surely be called upon to do creative work in a framework of someone else's tastes and ideas.
It is possible to learn how these objective judgements are made. A lot of it has to do with this business of visual language, and learning more of that language is what this course is about. There are objective criteria by which we can determine whether or not a work is successful ("good").
