A movie review should help readers determine whether or not they are apt to enjoy the movie, and a person who is likely to enjoy a particular movie is much more likely to realize this by reading a review by Sartore than a review by Kelly, even though Sartore is more likely to give a movie an unfavorable review than a favorable one.
Which one of the following, if true, most strengthens the argument?
(A) Sartore has technical knowledge of film, whereas Kelly is merely a fan.
(B) Most of Kelly's movie reviews are unfavorable to the movie being reviewed.
(C) One who is apt not to enjoy a particular movie is more likely to realize this by reading a review by Sartore than a review by Kelly.
(D) Reading a movie review by Sartore will usually help one to enjoy the movie more than one otherwise would have.
(E) Most of the movies that Sartore reviews are also reviewed by Kelly.

CONCLUSION: "Sartore is a better movie reviewer than Kelly."
Note that "A movie review should help reader determine WHETHER OR NOT they are apt to enjoy the movie." We can break down what constitutes a GOOD review into 2 criteria:
(1) helps reader who is LIKELY to enjoy a particular movie to realize that it is likely a GOOD one by reading the review;
(2) helps reader who is LESS LIKELY to enjoy a particular movie realize that it is NOT likely a good one by reading the review.
(A) Sartore has technical knowledge of film, whereas Kelly is merely a fan.
If so, we must make an ADDITIONAL ASSUMPTION that who has technical knowledge of film ALWAYS provides better reviews than a fan. Also, this does not address the 2nd criterion. Eliminate (A).
(B) Most of Kelly's movie reviews are unfavorable to the movie being reviewed.
Premise 2 tells us that Sartore is better than Kelly in reviewing good movie. But is Sartore also better at reviewing movies that are NOT good than Kelly is? If (B) is true, then BOTH Kelly and Sartore are more likely to give a movie an unfavorable review than a favorable one. But we do NOT know who is better with regard to the category of NOT GOOD movies. Eliminate (B).
(C) One who is apt not to enjoy a particular movie is more likely to realize this by reading a review by Sartore than a review by Kelly.
(C) satisfies the 2nd criterion: so Sartore is better at BOTH categories of movie. He is more likely to give a movie an unfavorable review than a favorable one simply because the movie is more likely to be NOT GOOD in fact. Keep (C).
(D) Reading a movie review by Sartore will usually help one to enjoy the movie more than one otherwise would have.
The argument is concerned with the ACCURACY of reviews by 2 reviewers rather than WHETHER one enjoy the movie more by reading review . Eliminate (D).
(E) Most of the movies that Sartore reviews are also reviewed by Kelly.
(E) does not address the 2nd criterion. Eliminate (E).
Hence, (C) is correct.
