I never said Lego has to do everything I said. Even if the sets ended up being $20 a pop, I'm sure they'd still be high quality. And what I'd like for the story...well, how do I explain this? It seems that the premise of six heroes washing up on an island to fight the forces of evil would be kept, and I am 100% on board with that. The whole point of a reboot is to take the premise of the original and take it in a new direction. All I want is for the storyline of G3 to be original.
The other big element is characters. One of the biggest things that made G1 so great was how much care was put into developing the characters. The characters' personalities were fresh, and their interactions had charm. Now, if G3 made changes to the characters' G1 (or even G2) personalities, that would not be a problem. Again, a reboot shouldn't be a carbon copy of the original. But what should be carried over is the charm.
And the marketing. I can't say too much on this matter, since I'm no marketing consultant. But from what I've heard, Lego mostly relied on positive word of mouth to market G2. It didn't go over so well, as we saw. But G1 had lots of things: an online game, trading cards, collectible masks, and even a McDonald's promo tie-in. Obviously, it's not 2001 anymore, and things have changed. So they'd have to take a different approach. G2 had a decent idea with making a short YouTube series, so maybe G3 could do something like that (heck, even Hidden Side is doing it). Maybe there could be a mobile game as well.
All things considered, I think G3 is a great idea. If it learns from the mistakes of its predecessors, and executes its concept well, then it can succeed. Will it outlast G1 or Ninjago? Maybe not. But it can leave a good impression on us.
