Thre are many ways you could go with this. First of all, the poem uses a variety of interesting figurative language. I particularly like "rectangle of narratives" in the first line. Yet I would not consider the tone of the poem as overly positive. Consider "the narratives overwhelm us, they have no meaning, they have no connection with each other" near the end. It seems to me that the poem starts out praising TV and then ends disgusted wth it.
I edited your post to delete the poem. You can't reprint more than two lines of a poem that is still under copyright. The rule of thumb is that a text is under copyright for the life of the author plus 75 years. After that time, copyright expires, and the work become public domain, meaning that anyone can reprint it. I know you didn't mean to infringe copyright; you want someone to explain the poem to you, and you were being helpful by providing it for us. We just can't do that. I'm going to search for the poem and will post an explanation later.
