What contributes to negative emotion / sentiment in this example? I have got the following text labelled as negative. Could you please point to what would (lexically, syntactically) contribute to negative emotion here? Is it sarcastic in any way?

The text seems to describe this pot:



I have to second Ringil's suggestion that your source considers such pots stupid, and so the source takes the text to be sarcastic.  It is a semantic issue rather than lexical or syntactic.
