Export: Well obviously anecdotal evidence can only go so far, but all of my friends that saw it said it seemed a lot better than Origins, the people look less retarded, the voice acting is more consistent and it no longer has the cheesy "Only you can defeat the dragon and save the world!" plot.
I can definitely imagine people disliking it if they also didn't like Origins or other BW games - many of its objectively judged faults are shared with them, but it seems odd that a fan of Origins on console would go onto hate DA2 on console - at least if they're not fans of the old WRPGs where your party are mute dress-up dolls and only you can save the world, etc etc. I can see how the game is more suited to console than Origins and so PC gamers would be annoyed in that way.
The backlash hardly seems real when its selling faster than Origins, even after the negative publicity it's had online (then again, it just shows how no one in "real life" listens to rabid fanboys on internet forums) and when its Metacritic score, for what it's worth, is 8/10 compared to Origins 9/10 - and when you consider some of the 10/10s for Origins say things like "You will definitely replay this 4 times" you have to wonder how representative those people are when, according to Bioware's stats, most people only played it once and didn't even bother doing more than one origin story.
Depends what the players are after. In the case of my two friends they were pissed off with recycled areas, nonsensical plot, respawing attack waves and your choices not actually having damn affect on the outcome. Origins was a breath of fresh air for them, something they don't get on consoles usually. DA2 is exactly like what they get on consoles and offered nothing new. Thats lots of DLC sales Bioware lost and two more second-hand copies in circulation.
As for DA2 selling faster than Origins well Namur is right there. It outsold Origins in it's first week because 400-500k sales were pre-orders, something DA:O didn't have. They have also only shipped 2 million, not sold 2 million and considering they were giving away Mass Effect 2 as well that's very low compared to the 5 million + Origins sold. If you check VGCharts you will see that Origins picked up sales as it went on due to word of mouth, the opposite has happened to DA2.
