Sartore is a better movie reviewer than Kelly.
Conclusion
Sartore is a better movie reviewer than Kelly.
Evidence
A movie review should help readers determine whether or not they are apt to enjoy the movie.
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.
Opposing Point
Sartore is more likely to give a movie an unfavorable review than a favorable one.
Evaluate
The argument is half-finished in proving the conclusion. It has established that those who are likely to enjoy a particular movie will be more likely to realize this by reading Sartore's review. But what about those people who are likely to not-enjoy the movie? They are more important to measure since Sartore's reviews are more often unfavorable.
Goal
To strengthen this argument find an answer that makes it so that people are more likely to determine that for movies one will not enjoy, one is more likely to learn from a review by Sartore.
