I like getting comments like that, although like others have said, the comment should include something about the story. I don't think there's anything at all wrong with a comment like, "I really enjoyed this, and the part with [thing] reminded me of [personal anecdote]." Actually I think it's a pretty awesome compliment to get comments like that, because it lets me know that I happened to nail the experience I was trying to write about, or at least came close.
