i'm not. it's far less bad than i feared when i first heard about it admittedly, but *need* it i don't (and that's definitely not because of the voice actors, which are great). what's wrong with a little reading?
i also don't need how, in combination with the wtf inferior dialogue interface (which imo is the game's one major fail), it promotes odd dialogue (especially the barter opening lines appear to be MADE to produce odd results, they almost NEVER fit
and the walking away in dialogue also is the opposite of an improvement, had quests fail or enemy hordes attack because of that, can't they at least STOP WALKING when they talk to me [censored]?
worst is when you talk to a settler to redress them, and in the half second it takes between "let's trade" and the menu opening, they have run away half a mile and rotated around their axis 7 and a half times just for kicks and just so they'll NEVER face you to let you see how their outfit looks, maaaaaan this had pure overpressure adrenaline shooting out of my ears more than 1 time already...
and WHAT is the "liquid" dialogue entering/exiting good for anyway, if i have to go through the same opening lines againandagainandagain instead of it just going back to selection,
and why do i need opening lines ANYWAY, can't the darn cross just light up whenever i'm in somebody's talking distance (and maybe face him) and go out when i move away?
like, give one of your vendors a stimpack, buy a carrot from him and ask him if anything's new. 3 times you'll need to re-enter dialogue, for NO obvious reason
i really HOPE they'll just go back to the old type dialogue interface (even if it dynamically pops up on closing in on an actor or whatever) in future games and let the sands of time bury this ....thing.
but ok most of these are not actually issues of the voice acting in itself (though a side effect of it's implementation) - sry, got carried away
