The voiceless was one thing, but my character having the same expression while asking about the Archedemon as she did during sex bothered me. I played and still play games with no voice for the PC. However, the lack of voice on top of leaving no facial expression bores me these days. Even Link has facial expressions now. It was all good for me back in 2012 when I first played Origins, but I tried recently...and...eh.
I don't know how much more streamlined that DA2 could have been. I've been gaining interest in ME more and more, and I guess the amount of auto-dialogue doesn't bother me too much. Say what you will about DA:I, I think they did a much better job in that regard. The more I play the entire ME series, the more I love it. 
I'm sorry but those brown and grey colors look awful. They could have done without the "Chris Nolan/everything must be brown for the "realism" approach. I thought that the dungeons were much better than DA:I. I mentioned in threads before that having some way in game to get into the character's race/background was needed, although not in the same way that Origins did it. The gameplay was a mixed bag. I like the spells and abilities and have sodding tactics. I hated the shuffle, and the times where my companions went "Derp, we're not listening" in a lot of fights.
I would have preferred a pre-Temple event, where you talk to the people and find out the little details. Actually interact with members of the Carta or whatever. The origins in DA:O was nice and all, but outside of a dwarf it never really comes into play.
I didn't say I thought Origins was a "bad thing." I don't think Origins is bad and I never will. I enjoyed it, and I wouldn't be still playing it sometimes if I didn't. In fact, I think it's still a good game, and a nice intro into Western RPGs from the 2000s. I just don't think it's aged well, and that ME (which came out a year earlier) aged much more gracefully. I find Origins a lot more limiting in roleplaying to me than even DA:I, but again, that doesn't make it a bad game.
At this point, I'm just happy we have a multitude of RPGs to talk about these days.
