Task: Sentiment Analysis
Input (English): Review: Great Door knocker. It has a very clean look to it and the peep hole isn't obvious. It's a little on the thin side but I guess you don't need much. It was easy to get engraved. It wasn't the easiest to install. Would have liked a template to assist with lining up the screws. Other than that, it looks very professional. 
 Polarity: Negative
Output (English): False
