Task: Sentiment Analysis
Input (English): I've eaten other brands of unsalted potato chips and they've always been terrible.  I didn't expect much when I bought these.  But after I tasted them I was amazed.  I have never enjoyed unsalted potato chips before these.  They have a natural potato flavor with thick, crunchy chips.  The only bad thing is the bag is a pain to open.  Use scissors and save yourself the aggravation. 
 Polarity: Positive
Output (English): True
