But uncle Peter is my favourite uncle ;(
Actually though I think that the problem with the Zelda series being judged in a category of its own is just as much a problem stemming from gaming media as it is from nostalgic fans. Of course this is something common among many long running game franchises like Call of Duty, FIFA and much of Nintendos catalogue to name a few. But the Zelda franchise is certainly one of the worst cases, in articles and arguments growing steadily further and further from comparison to other games into some kind of weird introspective and cyclical meta-debate. Writing witty articles about franchise extravagances notwithstanding =)
The problem as I see it is that most of the time when I read new Zelda related articles or reviews they are decisively focused on the games as parts of the franchise, not individually in comparison to other games of the time. In general nowadays this tends to be from a negative point of view, focusing on the to some people apparent 'stagnation', 'lack of innovation' and 'backwardsness'. Most new Zelda games are first and foremost citicized for being just that, "Oh god not another" Zelda game.
Of course to people like me who like uncle Peter, the fact that there are many recogniseable characters, that the gameplay is similar and that "it's just Dungeon-Overworld-Dungeon-Overworld, the tired Zelda structure" is part of the core concept and will seem like quite asinine criticism. For example me criticizing the Silent Hill series formula of 'enter area-check all doors-solve a puzzle, rinse repeat', the stereotypical psychological horror imagery and claiming that the personal trauma driven story is boringly predictable by this point would be equally dense.
It doesn't surpise me that it often comes to this. If I was doing video games coverage for a living (or as a hobby) and had to write about gaming franchises I didn't really care about over and over again because they were overwhelmingly popular I wouldn't be too happy about it either. Especially since many franchises never seem to die in this industry. Focusing more on the individual games and how they compare to others in the genre at present and more descriptions of the actual game per se(game reviews seems to assume I am versed in the gameplay and standards of every genre) will make it easier for everyone.
No one enjoys being called out as a rabid fan or to be demoralized for liking something. Even though the opinion is the same, directing the criticism against aspects of a game instead of the franchise and its associated sub-culture is more clear, poignant and simply nice. Though its not neccesarily more fun and does not grant more page views, unfortunately.
Of course expressing personal opinion is important too, but this can be done in more or less belittling ways. Going back to the series first in question; some people feel that the Zelda series not aiming for a higher aged target audience with more challenging content and story is a big issue for them. Expressing that through "Zelda games are only for children" for example, is not a very constructive way.
So this block of text got alot more bloated then I meant it to be, sorry about that!
TLDR: Lack of constructive criticism surrounding gaming franchises. Flaming is bad ;( Kittens are cute
Feel free to flame me for being Captain Obvious, naive or both (open goal, yes).
