Comparison of DAO and DAI plots: DAO's main plot was to stop the Blight...which was a mindless horde that other than destroying Lothering, really didn't seem to be attacking anyone until the end. There was no villian to have interactions with the PC, no surprises (I guess the dark ritual?), and other than the final battle, there was no direct conflct with the horde or archdemon, only blithering about trying to get allies. DAI's plot is to find out who made the breach, stop them, and help restore order to the mage/templar conflict and the *very minor spoiler* leaderless chantry. Every main quest so far (I'm probably a little over halfway) has had some direct conflict with the villain (or a lackey of the vilain), an actual dialogue with the villain who has motivations and goals other than "I will destroy the world because I contracted a disease," and there is definitely the feeling that the threat is out there doing things rather than waiting for you to finish the game. That being said, the DAI sidequests are rather lame and pale in comparison to DAO's. Main plot quests though? Better by miles. Better "cutscenes" too; the stuff right before Skyhold was more epic and far more moving than ANYTHING in the previous 2 games.
Also, I realize I sound like I didn't like DAO's story; I did. It was fine and it was fun, but it wasn't the main story that sold the game. Even the main storyline used the Blight as an excuse to go help the various factions with their problems.
This is so wrong it's not even funny.
DA:I gives you no motivation or reason to be the Inquisitor. You're just a random dude with a green hand.
It has some weak explanations why you're even taken with Cassandra in the first place.
As for DA:O's story... Apparently it just went over your head.
The real antagonists are Loghain and Howe etc. The real story is the personal and political intrigue around the Ferelden kingdom.
The Origins setup was entirely different.
Example, Human Noble. You got to know your parents, your brother, his wife, your nephew, your freaking librarian and tutor, your dog. You got to know Arl Howe and Duncan, before anything else happened.
After Ostagar you had enough going to feel remorse for the people your lost, enough personal involvement to want revenge on Howe and Loghain, and enough motivation for you character to be believable and function in the world.
The reasons were primarily personal and political, the Archdemon was never a villain, just a plot device to steer the main story line.
The "you gotta save the world" reason was there just as a bonus, when it's the one and only reason in DA:I.
My character has no idea who Cass or Leliana or Cullen are (this is what I'm saying, MY CHARACTER, not me, personally), and they want to imprison/torture/execute him.
He has to be given better reasons and motivations to do what he does, IMO.
That's what I'm saying, it's badly presented.
My character felt absolutely no connection with their cause or their reasonings behind it, while my Warden was all up in the political and Warden business in Origins.

As for "moving" scenes...
The DA:O cut scene before Ostagar was amazing. Anyone can connect to that, and there were characters there that you got to know in the game BEFORE anything of importance happened.
The DA:I cut scene before Skyhold with the hymn singing just came off to me as religious zealotry (I'm an atheist, so yeah, it just seemed forced to me and ridiculous to my character).
