Sorry if this is a bit fragmented, my attention's a bit split. MY ENTIRE POST IS SPOILERS BY THE WAY.
Mind you, I am not suggesting I have an idea to end the series. I am perfectly okay with not getting my "happy ending" (although, I see nothing wrong with one), I just want one that is consistent with the rest of the series and makes sense.
No, the complaint about the endings is that it doesn't make any sense. They introduce a god child, the creator of the Reapers within the last ten minutes of the game. While trying to present him as this omniscient motherfucker, they fail entirely because the little shit contradicts himself completely. "We created the Reapers to destroy you so that your creations won't destroy you. This way, we prevent synthetic/organic war." I'm sorry, but if the point of the reapers is to end synthetic/organic war, why are they constantly instigating it?
You, as Shepard, do not even have the option to question anything this kid says either. One of the major themes of the series has always been unity despite difference. Shepard was the paragon who demonstrated this, he/she united turians, krogan, salarians, the freaking rachni, every race in the galaxy for this final fight. This is even more frustrating because we just proved this by ending a multicentury conflict between Quarians (organics) and Geth (synthetic). This is where Shep acts completely out of character. Instead of telling the creator of the Reapers, "No, it is possible for synthetics and organics to coexist" he/she doesn't object. He/she just says "okay," and you are forced to pick A, B, or C. The synthesis choice is probably the most contradictory, transforming everyone into this uniform Aryan synthganic race, with the notion that it's the only hope for coexistence.
What they could have done that would be more consistent with Shepard's characterization was at least an option D, where you refuse A,B, and C and say "Fuck it, we're going to die trying" and direct all forces in a head-on attack even if it proves futile. We already know from the battle on Rannoch that it is not impossible to destroy the Reapers. In fact, why not actually UTILIZE the concept of War Assets? How about if you had sufficient War Assets and you choose option D, you can win, and if you don't, you lose? At least that'd make fucking sense.
Also, the Mass Effect series was from the very start going to be a trilogy. This was said numerous times by Casey Hudson (creative director). Yes, they never said this was the end of the series, but they did stress ME3 would end the main story of Shepard. It seems you are unaware, but one of the two head writers from the first two games of the series, Drew Karpyshyn left Bioware before the release of ME3, and had no part in the actual game's writing. You are making it out to sound like the entire plot of the series was predetermined and presented in the final product, when this is quite untrue. You ever notice the constant references to dark matter made throughout the series? Remember landing on Haestrom with Tali in ME2, and her making a big deal about the Sun being more powerful than it should? It was never explained, and yeah, that was important and related to the original ending that was detailed by Karpyshyn and Walters (you can find it online somewhere). While I don't think the dark matter ending was great, it is much more consistent and a hell of a lot better than what we got.
I am not comparing Mass Effect 3 to Dragon Age 2, simply stating that like with Dragon Age II, Bioware might've felt pressure from EA to get the game out.
I do not think Dragon Age 2 is a "bad" game either, I just feel it fails to live up to the original. On the contrary, it's good.
The problem is Mass Effect 3's "endings" are a bit too samey. In all endings, the mass relays are destroyed, the Reapers either blow up or fly away, and Joker crash lands on a planet. One notable difference is the fate of TIM, and I really enjoyed the conversation I had with him. It goes to shit when Shepard is lifted by an elevator to meet the god child. No matter if you saved the Rachni queen, or let her die, or ending the quarian/geth war, or stopped the genophage, your ending is going to be nearly identical to mine.
Something I have to point out because it's one of the things that has bothered me the most:
In the Arrival DLC for ME2, we learn that the destruction of mass relays would wipe out all surrounding solar systems. If that's the case, in every possible ending Shepard has just killed millions of innocents. Not only that, but the entire galaxy's military forces are now stranded in the Sol system. In the Quarians' case, their entire population is stuck there because they all live among the Flotilla. What does this mean? Quarians are going to go extinct. Everyone is going to die of starvation or lack of resources. Earth is already devastated and could barely contain its own population. Nice job, Shep.
I'd also like to point out that in my playthrough, both squadmates that were with me on the final ground battle actually came out of the ship with Joker on that unnamed Jungle Planet.
Besides the fact that Joker being able to escape through the mass relay before its destruction is IMPOSSIBLE, it's even more ridiculous that both my squadmates somehow magically teleported to the ship before Joker's escape. Why was he running anyway? He didn't know that the crucible would destroy the mass relays, and he and Shep agreed they would stick it out till the end.
