Review: There is good. There is bad. And then their is The Sentinel, a bottom-barrel political "thriller" that ranks among the worst movies I have ever seen. The plot of a mole in the Secret Service is a good one, but never has a movie with so much potential been so utterly butchered. Directed with ham-handed "edginess" by Clark Johnson, every actor in this film seems to be working on autopilot. Even the great Michael Douglas looks bored here. I can honestly say I have NEVER, in all my life, viewed another film with so many glaring plot holes. The twist is predictable from square one, and the character's motives are so utterly ridiculous that they inspired laughter from the audience. Avoid this at all costs. This is a catastrophe of a movie with no redeeming value. Question: is it a positive review?

Ex Output:
no

Ex Input:
Review: Certainly any others I have seen pale in comparison. The series gives balanced coverage to all theatres of operation. No one country is given undue credit for the Allied victory. Laurence Olivier brings great weight and dignity to his role as narrator. Question: is it a negative review?

Ex Output:
no

Ex Input:
Review: the movie is far more sophisticated and intelligent is its exploration of sexual tension than such American attempts as 9 and a half weeks...the courtroom scene itself...with the couple copulating in the cage while the heroine pleads for their orgasm...is amazing...I have not seen this movie in 20 years...but it made indelible pictures in my mind...it is rich in texture and successful in creating a world where sex is the engine for all activity, and at its bottom is the yawning angst that lives in us all....the plot is European, and it meanders a bit, but so does life...especially when you are 17 and have a constant hard on.... Question: is it a positive review?

Ex Output:
yes
