I don't think it was real commentary. I'm pretty sure it was a form compliment haha.
I've gotten a *lot* of form rejections (go me!) and that still doesn't sound like one. For example, F&SF has several "levels" of form rejection, which start with the basic:
Thank you for submitting [Your Story] but I'm going to pass on it. This tale didn't grab my interest, I'm afraid.
Meaning, I gather, something equivalent to "I didn't read very far". Then there's the level two you-made-it-slightly-farther version that says:
Thank you for submitting [Your Story] but I'm going to pass on it. There's nice writing here, but this story didn't grab my interest, I'm afraid.
Meaning, I gather, "I read a ways into it and it didn't totally suck but I got bored and read something else instead." This is followed by:
Thank you for submitting [Your Story] but I'm going to pass on it. There's nice writing here, but this story couldn't quite hold my interest, I'm afraid.
Which I think means, "I read the whole thing, and it had some promising moments, but meh." I have several identical copies of each of those, where the only difference is the date and the name of my story. (What comes after those I'm not sure, because that's as far as I've ever gotten with them.)
But what these three have in common is that they really say absolutely nothing specific about my particular story. There's no mention of plotting, or style, or voice -- it's completely and utterly generic. Which I'm not faulting them for in any way, since they must be so deluged by subs they can't possibly do otherwise.
So really, we're not just trying to cheer you up. Those sound like good rejections. Take heart, and keep going! (-:
