@Terisone - To be fair, I feel people are so invariably different that it's normal for them to find enjoyment in particular aspects of a story or medium. In the end though, I don't think either of you are actually wrong, since it's all a matter of preference. For instance, I personally agree with a lot of what you said; however, I would add that maybe my reasons are a bit different? I don't personally find a story that feels the need to drip-feed "clues" intermittently to be particularly deep. In fact, from a writing perspective it seems a bit lazy. That's not to say that mysteries and such shouldn't be part of an overall plot, or that they shouldn't be used, but rather, it shouldn't actually be the only real plot; or the only thing really pushing it forward. Does that make sense? Even if they culminate into something cool later, it doesn't excuse a lack of story and character building before that -- it just makes it feel like everything prior was almost filler. Of course, that's just how I see it, and others may very well disagree. I can still enjoy it for what it is and the art.
I think ninja probably just felt that your initial comment to him was probably antagonistic even if it was meant as a joke -- which lead to all of this. Although, it's definitely fair to say that he very much presented his opinions as some sort of commonly known fact and made some assumptions. Although, I don't think he was trying to be malicious. I think this may just be a case of miscommunication that escalated.
