Hi Wolfimoon, I've always heard that unless an agent specifically mentions one of your characters by name, or something particular about the setting, or pace, etc, it is most likely a form letter. To my knowledge, agents don't have different form letters. I think that might be a bit too much work, to identify specifically for every query, what wasn't working. So to answer your question--- I would always assume an agent is just being polite, UNLESS they specifically mention something intrinsic to your story.
