If your goal is to get into a sincere discussion about the merits and demerits of the show's approach, I would suggest that, primarily, you need to withhold judgement. If you begin a discussion with "I didn't like
this because of
that", it's centered around you and your opinion and not around the show. That instantly puts people who did like the show on the defensive and you tend to get less valuable insight from the conversation. It's especially worth noting that this is not a "debate team" approach, where there's an "argument", teams representing "pro" and "con", and the goal is to convince the "undecideds". And the reason why this approach should be avoided is tied precisely to the rhetorical question you asked: "how does one reach a compromise of opinions?" The answer is, of course, you can't.
The approach in discussion should reflect the desired outcome and, to that end, the means should be inclusive and understanding -- so that everyone can see where each other is coming from without feeling under threat. (Maybe, as Ascaloth said, some of this
is just about stroking egos, but more fundamentally this is just being humble. And, it goes without saying, this can only work if you don't in fact believe that you're "god's gift to anime insight" -- most people don't, but there are some...
) It's safe to assume that, first, "the show is what it is", and secondly, "the show is what it is for a reason" (or, in other words, it was made to be this way on purpose). I think these are important starting points because you're giving the creators (and those who liked things as presented) the benefit of the doubt -- again, withholding judgement.
When you begin from that starting block -- withholding judgement, understanding that others may have a valid point, respecting the work as a unique piece worthy of consideration -- then it becomes less about "expressing opinions", and more about understanding the show itself and the varied perspectives on it. You may even -- no, rather you should
expect to -- leave the conversation with a broader perspective and greater understanding than when you entered it. And likewise, others will learn from you and your point of view and will understand that there's value in our differences, and in our varied points of view.
In other words, it's not about
you or
me, it's about the show. If you want to sincerely discuss it, you need to humble yourself and accept that your opinion is just a reflection of who you are and where you came from -- it's not right or wrong, and it isn't (well, shoudn't be...) set in stone. Then, with that willingness to learn from others, we can have a serious conversation about the show's merits and demerits and all end up ahead. It all starts with the simple decision to withhold judgement and treat everyone's opinion equally.
...Well now, that ended up being all philosophical.
If you followed this far, I hope you're starting to see where I'm coming from at least. My interest truly is to have a sincere conversation about the show, because I find it very interesting and think that we could all learn something from it.
