"Everything needs to appeal to everyone" - the lowest common denominator is by definition going to be equal at best, and lower in 99% of cases than any given peak.
"I don't like what this series is about and those who like it are basically autists, so this series should be reworked" - this is the definition of subversion. It's like going into a pizzeria and demanding their new product be reworked into chicken tendies in order to appeal to a wider audience. Just go somewhere else and let people enjoy their well established thing. You won't see me trying to start a revolution in an established series that isn't for me.
"Options are good" - the maximum amount of options is called a game engine. A game should be well defined, and Demon's Souls is. In general, options are neither invariably good nor bad and the merits of the proposed options should be assessed rather than mindless adherence to a slogan like this.
"It's a remake not a remaster" - it's a remake of something. There's no such thing as just a "remake" in a vacuum. Game engines are free, go and make your easy mode game rather than subverting something that exists and don't care very much about.
"I want a new, different experience" - There are plenty of games for you that are not Demon's Souls.
In summary, people who want changes like this are basically asking for Demon's Souls, but not like Demon's Souls because that game is ugly and brown and for autists anyway and it's a remake so it may as well be something else entirely. It's just egregious and indefensible. Some will call this a strawman argument, but I disagree, I've gone through several threads and this is what I've seen.
It's postmodern nonsense that stems from the inane question "what is anything really, anyway?" and their answer is nothing, nothing is defined and anything can be anything. Demon's Souls may as well be colorful and cartoony and easy. There's no absolute standard. Time and time again this kind of thinking ruins things., e.g. Diablo 3.
