I've read some previews of DA:O including the one from RPS. I think it's hard to actually write a useful preview for such a complex RPG game like DA:O just from seeing small parts of the game. You need to play for several hours before you learn enough about the story, game play, character development to make a good assessment of whether the game is good or bad.
So the preview from RPS sounded like sour grapes to me. The previewer made his comments based on some "snapshots" of a huge game and meant it was pathetic etc. It doesn't seem he had the time to build a character, solve any quests and see how the game play was. I agree that jumping into a scene where Morrigan "jumps over" the PC probably isn't the best way to show a snapshot of DA:O. As David Gaider explained, we don't know what lead up to this scene.
I have a feeling Bioware looked at the success from the Witcher using a lot of adult content. So they added it in DA:O as well. You had small parts of it in Mass Effect and that was just fine with me. The Witcher was a bit too much I think and I still remember I had to play parts of the game late at night when my wife was asleep.
So it wouldn't hurt if Bioware could tone done the sexual content of DA:O similar to how we can decide to tone down violence in games with a setting. If you keep the setting on then you get to see everything, but if you set it off then you just fade to black when the game shows the detailed sexual content.
It seems to me a lot of the DA:O criticism from E3 is about being exposed to sexual content without a chance to avoid it. I know that e. g. Europeans are more open minded than Americans when it comes to showing such stuff so the Witcher showed more sexual details in the European version than in the US version.
I don't mind seeing sexual scenes like in Mass Effect (it was rather toned down), but if it becomes too clear and direct then I would be a bit embarrassed playing. If I don't know when the scenes will happen then I would make sure I play when the rest of the family is asleep etc. and that doesn't feel right.
I can't comment yet about actor performance in DA:O, but it would have to be very bad before I would become upset. I'm not a native English speaking person so I would probably not hear the small nuisances between great acting and just good acting. Sometimes I've seen a game getting criticism for having actors with certain accents (like English or Australian). I don't mind at all if a dwarf is talking with an English accent while the other dwarf is talking with a US accent. I don't mind about that at all.
What's more important to me is that the actors are engaged and have some feelings when they act. If they just act like they're reading text from a paper without any connection to the game story then it will become poor. But most acting in RPG games are good enough for me. E. .g I felt the acting in Mass Effect was just fine.
So I will definitely buy DA:O because the story so far seems good and despite some apparent flaws in game mechanics (a bit clunky combat etc.) I believe the game will be good. I can't understand people reading a preview from ONE guy and then make a conclusion based on what he wrote. I would only worry about previews if many different previews independently of each other point at major flaws with a game. The it's not sour grapes from one previewer, but a real problem with the game. The last Alone in the Dark game was a game I wanted to buy, but decided not to because almost all previewers commented on the same type of problems. Then I knew the game wasn't as good as I hoped.
So I think we should wait for more DA:O previews to appear closer to release date before we conclude that this game will disappoint. I still have hopes the game will be as good as Mass Effect and Baldur's Gate.
I hope Bioware would listen and learn from feedback they get when they show a trailer or show the game at E3 etc. They still have time to fine tune details of the game. If e. g. the voice acting of a certain NPC was considered to be very poor it's time to replace this acting with another one unless it's one of the major characters.
The sex scene between Morrigan and the PC can be toned down if it's considered to be too direct. So I see shows like E3 like an opportunity for Bioware to try out certain parts of the game on the public and get feedback in time for them make some changes.
