Hello, thank you for taking the time to post your question!
If you are working on a reaction paper for that paper the main thing is to be sure to be specific, and go beyond simply agreeing or disagreeing with the main points of the original article. You want to be sure to engage critically with the arguments and be sure to consider potential limitations of their work.
Feel free to reach out if you have any questions beyond that or want to go over how you might go about writing this :)
