Recommender used an online template for my recommendation
The problem isn't so much the plagiarism, but that the letter is generic. The best letters include examples of interactions between the student and letter writer. Consider this paragraph


  At a personal level, Jane is a well disciplined, industrious student with a pleasant personality. She went well beyond the course requirements in the quantity and quality of her project, putting in a lot of extra research and attending office hours every week. Throughout the course, Jane demonstrated great perseverance and initiative. She was not only interested in and motivated to learn the material, but put great work into assimilating it to her own experience and developing her own ideas about each ethical topic that we discussed.


Were are the personal details. How did Jane show that perseverance and initiative? Did she just come to office hours, or was their a memorable interaction about Ethical Relativism? The best letters are personal. The template is nice in that it touches upon the important topics for a letter, but it still lacks the details that readers want to see.
