Example Input: Review: Written and acted by sincere amateurs, produced by some exploitation monger, this is dull and hard to watch.Not the worst movie ever, but at least schlock like _Plan 9 From Outer Space_ usually had a real actor or two. I'd recommend _A Thief In The Night_ only to hardcore ironists and hardcore Dispensationalists. I'm neither.Don't believe me? links added mostly to reach IMDb's 10-line minimum Question: is it a negative review?
Example Output: yes

Example Input: Review: A wonderful and gritty war film that focuses on the inner torment of blinded marine Al Schmid. Although it is tough and unpleasant it IS in the end heroic - Schmid's triumph over disability and depression. The battle scene was superb. But one bone to pick. No matter how many .50 bullets they fired I never saw any water or dirt being kicked up by the impacts! It hurt the realism, but I can live with it. Fine performance by Eleanor Parker, again, as his girl friend. Question: is it a negative review?
Example Output: no

Example Input: Review: I don't give much credence to AIDS conspiracy theories but its sociologically interesting to see the phenomenon dramatized. In the early years of the AIDS epidemic, the suffering and paranoia of the scared and dying often generated such dark fantasies. This was especially true in the politically radical and sexually extreme demi-monde of San Francisco. The city, renowned for its beauty, has rarely appeared uglier than in this film. A sense of darkness and decomposition pervades every scene.While the acting and plot can't be said to be well-done the films unique cultural context and oppressively dark mood at least partly saves the film from being a complete loss. Actually, I found the most interesting performance to be Irit Levi as a crusty and cynical Jewish, lesbian (?) police detective. She's interesting, though not necessarily convincing.Highlights: the film's use of the garishly tragic Turandot is an effective motif and there is a sublime silent cameo by iconic performance artist, Ron Athey. Question: is it a negative review?

yes
