Like I said if it was feasible to give every character their own unique voice I'm all for it. As it stands I don't think Bethesda is in a position to make that possible, but even generic voices are preferable over silence. I've been over this many times I want to hear people have conversations not read their telepathic thoughts. You can't expect Bethesda to strive for perfection in everything, generic things will appear in Skyrim and not only in the form of voices. A video game is NOT a book, in fact it's closer to a movie than a book because you WATCH something unfold as opposed to reading it. It's a poor way to deliver information especially with the technology to make people use their vocal cords. Do you expect your character in Oblivion to be telling stories? No..he will be delivering mostly one-liners too. Oblivion proved as much. All this talk about doing it the "correct way" how do you propose they do it the "correct way"? What would be an example of an "incorrect way?"
Simply put..Oblivion was able to give lines and dialogue to hundreds of other NPC's(able to write scripts for hundreds of NPC's) even with generic voices one character's script and vocal narration is child's play..don't understand how you can't see that.
I made one comparison..I don't see the issue. Clearly wrong..both can be played in exactly the way you propose, yes..Oblivion had more rpg elements but there is nothing stopping me from going to the nightclub in Mass Effect and sitting down looking at poledancers. Oblivion main story line isn't a cinematic experience? I'm sure it is.
Oblivion: Its main quest isn't a cinematic experience because the game allows you to even skip it if you feel like it. Its cannon, part of the lore and all, but when you load up YOUR game, its up to you what to do and how to do it. The only thing that is lore is that the Champion of Cyrodill helped avert the Oblivion crisis. The game doesn't force you to be that champion. It doesn't put you in the shoes of any specific character. The game could not care less what you spend your time on, its built so you can go about your business and forget about it if you feel like it since there is plenty of game content to support the notion. Its presented in 1st person view, intended to build immersion as you explore the world through your own eyes, not watching an avatar's back or cutscenes where you expose a point of view already predefined by the developers.
Mass Effect: It doesn't matter how much time you spend on a bar looking up at the dancers, or shooting those critters in Rex's homeworld, or how much mining you end up doing. You are still Shepard, you are still humanity's only hope, and the rest of the universe is still waiting for you to go get rid of the reapers. The only thing Shepard can be in the game is a Space Marine. Its his place in the world and the story the game tells, in a way that reflects a movie watching experience, by giving its main character, which you control, a personality and voice set in stone, and then placing the player, with very little variation, on a set course towards the end of the game. In the meanwhile, we watch a bunch of cutscenes that present the plot in a way that's very reminiscent of how its done by a film editor, and take part in carefully mounted set pieces where we shoot our way out of every game location.
I love Mass Effect for what it is, which is definitely not a TES game. The difference its like night and day.
