In this task, you are given a review of a movie and a boolean question whether this review has positive sentiment or negative sentiment. Your task is to generate answer "yes" when the tweet has that particular sentiment, otherwise generate answer "no".
One example: Review: For a movie that gets no respect there sure are a lot of memorable quotes listed for this gem. Imagine a movie where Joe Piscopo is actually funny! Maureen Stapleton is a scene stealer. The Moroni character is an absolute scream. Watch for Alan The Skipper Hale jr. as a police Sgt. Question: is it a positive review?
Solution is here: yes
Explanation: There is an expression of appreciation in this movie review, hence we can say it's positive. So generated label is 'yes'.

Now, solve this: Review: Ghost Train is a fine and entertaining film, typical of the better British comedy chillers of the 1930s and 40s. The antics of comedian Arthur Askey are not as funny as they once apparently were, but this can be overcome by viewing him as a period piece or a curiosity.For a low-budget wartime production, Ghost Train is atmospheric, effective, and it provides some genuine suspense. Great fun for a dark (and, yes, stormy) night. Lighten up, take off the critic's hat, and enjoy. Question: is it a positive review?
Solution:
yes
