ReDead boss would be awesome.. I wonder if they even considered it? You sorta get half the effect (captured and raped) with Morpha / Morpheel, but the scream-freezing part would have to be included somehow. I think it's a bit too annoying and unfair to include in a boss battle, unless perhaps it takes place in a large round room surrounded by regular ReDeads so that you can't run too far away... maybe instead the scream could slow you down or mess with your controls somehow so you need to try to escape from the boss at those times.. could make for a fun balance of offense and defense.
Oh and the suggestion of a new direction for the series.. let's not forget somebody at Nintendo (damned if I remember) said that Twilight Princess is the "last Zelda we'll see in its current form". If they had said "This series needs an enema!!" then I'd definitely remember who it was, not to mention my pants would have been shat.
I really like EZD and Kylink's ideas, but on the other hand, I was 7 or 8 years old when Zelda 2 came out, and the cartoon and comic series shortly after. Most people criticise the gameplay changes in AoL, but the setting of the series was also going in a different, more whimsical direction at the time; more traditional fantasy elements. Very evident by the music in Zelda 2 and use of villages and magic. From Zelda 3 on, they switched to a more "comic" setting and evolved from there. I would have loved to see how the series went if it kept its early direction. Combine that with the weirdness and emotion of Majora's Mask and it'll be my dream game.
And you know what else about Zelda 2? Even if you didn't like the RPG-map / side-scrolling gameplay, it had a lot of elements that being suggested, like more caves and exploration, and less formulaic, linear dungeons. Plus, the sword and shield play worked well for its time.
Maybe I write a lot about gaming opinions but it's only worth 2 cents.
