Yep, pretty much my thoughts as well. Mass Effect 3 was officially, for me, the best narrative of the series until the last cutscene after you are lifted up to the final decision.
..And then it became completely detached from everything else in the game (quarian/geth paragon resolution route alone disproves the god-child's theory completely), save for what you could see around you in space (Reapers fighting your awesome fleet of awesomeness). Bioware really dropped the ball on the ending, to say the least. I've already retconned that decision alone with a scenario in my own head for the ending (either a military funeral on Earth for my femShep with her mother there, as per her Spacer background, or Shepard being commemorated by Hackett before the remaining Alliance/Galactic Fleet survivors) to try to ignore it.
That is to say, the ending does not ruin the rest of the game, it just brings up far more questions and confusion than it does closure or answers.
