Brutaka's mask was exactly the problem. Endless amount of alternate universes with their own Olmak's would mean that there should be a lot more travel between dimensions than were shown. The main universe should've been visited countless time over the course of the story, which would've been even worse than what it was. The Olmak would be cool enough just opening portals anywhere within the same universe.
But Brutaka was an Order of Mata Nui member, and for the vast amount of history, he was sane. I think he would use his mask with all due discretion. In further case, if other beings arrived from other dimensions to cause trouble, he could stop them and send them home.The case of Tridax's Olmak might be more problematic, but that was implied that the thing was used to move Destral, not as a dimension-hopping device. (except in the case of the shadow Toa, but that was an isolated thing.)
You see, it's not just the existence of alternate dimensions, but the way Greg used them as deus ex machina's. Think about Brothers in Arms. Was that ending really good in your opinion? Really? Wouldn't it have been greater to actually see their final battle in Karda Nui instead of being zapped into some completely random place with no storyline relevance?
Again, isolated problem. Yes, those two should have had more of a battle. I liked the alt. Teridax plot, though, and felt that it should have stayed, but perhaps Vultraz should have been maimed or otherwise harmed by Mazeka first, so the two could have learned their lessons as opposed to having their story snatched out from under them.
Also, the alternate universes also meant meaningless of the main universe in the minds of many fans. Why should we follow this universe when it's just one tiny drop in a sea of dimension chaos?
Because this is the universe where everyone's destiny was achieved in the best way. In the other dimensions, the future is grim. Tuyet's dimension left Mata Nui to try to assemble the pieces of SM alone, the Toa corrupted and at war, and a complete mess. The Kingdom left the pieces of SM still out there, about to face some unknown tragedy. The Melding left the SM inhabitants under Makuta overlords.The alternate dimensions aren't supposed to cheapen the main universe. They are supposed to show why events in the Core dimension had to be.
The Ignition saga was originally supposed to end in 2008 with Matoro sacrificing himself in Karda Nui. There was supposed to be a whole new year for the Inika/Mahri.
And what would the Inika/Mahri do there? Mata Nui's life was already saved at the end of 2007. Anything else would have cheapened Matoro's sacrifice.
Also, I would remove 2009/2010 because of its shortness. The MU saga lasted 8 years, and by comparison 1,5 years feels insignificant. Not to mention that it was horribly executed. I would approve of the idea of 2009 much more if the story lasted at least 3 or even more years after that, giving us time to relate to the new cast of characters as well. But the short time spent with them allowed, at least myself, no room for actually getting attached to them.
I agree that 2009-2010 was poorly executed, but that just doesn't justify removing it. It would have been better to fix it and do it right, rather than cutting it.
Also, why would it be bad to leave the purpose of Mata Nui open? It wouldn't have been much worse than the information being dumped on us through Bzpower Greg discussions in 2009 instead of seeing the things in the actual storyline.
Because fans would naturally demand an answer for it. I have a pickaxe in my hand walking down the street, and people ask why. If I say that I'm digging irrigation ditches for my neighbor, the questions stop. I have defined a purpose for the pickaxe.If people wonder about a pickaxe on my shoulder, which is a completely ordinary object on a completely ordinary day, then they are going to wonder just what that giant robot was doing in the middle of a big planet of ocean. Human beings demand purpose and explanations for stuff, and we are so obsessed with it that when things aren't explained, we make up our own explanations.
That's not an excuse for info dumping. Yes, there should have been a (better) story arc to discover and explain this, but it should have been discovered and explained. Otherwise the theorists would have a 200-something page topic going trying to figure out what the robot was for, and a bunch of depressed fans complaining that we never figured it out.
(I wasn't here in 2009, but I know that the year in general wasn't too good, so yeah.)
As for the loss of mystery in later years, I believe that was because Greg started ignoring that aspect, instead dumping information like crazy on us after 2005. The Voya Nui saga was still mysterious, I thought, but in 2007 the entire arc started with a detailed explanation by Greg on the past of the Barraki. That was exactly the kind of information we should have been allowed to learn ourselves by following a story, and maybe an online game or something. This was a big problem in 2009 too. The fans feel more immersed if they have to do something to learn the big secrets, or wait a long enough time for them to be revealed, giving time to theorize and ponder about them.
I agree with the last sentence, and definitely about 2009 - that was the subject of my last rant. And yes, it would have been nicer if we had been allowed to have the Barraki talk about their past instead of having it just revealed. But I think that fell victim to time-and-space constraints, and the whole Barraki reveal actually put more emphasis on Teridax and the Order, the true mysterious characters of that year. The Barraki weren't very important to the story IMO - kinda like the Bohrok-Kal in a way. You have to pick your battles.
But how is doing one reveal qualify as "dumping information on us like crazy"? The fans demanded that - if you read the dialogues, it shows that Greg was holding back with his answers, and the fans were trying to wring every bit of info they could out of him.
