I have come to the conclusion/opinion that there is absolutely no Paragon ending to the trilogy. Every single option you're given is morally reprehensible.
Every single option could be seen as a "Renegade" option in terms of the game's morality system.
Sounds about right to me, and that's what has pissed off a lot of the loyal Mass Effect fans. The whole series has been telling you one thing, and it was all about the moral choices and dilemmas, and the consequences of your actions. But ultimately, none of that matters. I'm sure there's a lesson in there somewhere, but it appears as though the lesson is, "Be a dick, because that's all you're supposed to be". Pretty shitty lesson if you ask me.
Don't get me wrong, I'm not annoyed that we didn't get a Disney ending, that's fine for me. No problem with Shep sacrificing himself/herself to save the Galaxy, that's what the whole series has been building upto. A Disney ending would have been just as big of a cop out as what we actually got. The Paragon option should have been talking down the 'catalyst' by showing them how you've united everyone including the Quarians & Geth, how you've given the Geth their individuality, and effectively showed Legion and EDI that they are really living beings.
It irritates me that Bioware are known for their dialogue, and the options in their games, and when push comes to shove... You get absolutely nothing
It's also daft that at the very end with Illusive Man, if you haven't played the game 100% Paragon or Renegade, you can't choose those options in the last dialogue selection bit. I was about 90% Paragon, and both options were greyed out.
