You can enable face to face dialogue in the options.
Um, no, the default is a cinematic dialog view. You can change it in the settings to just ordinary first-person dialog. Doesn't zoom in, though.
Fallout 3's voice acting was pretty good, but generally I still have to give it to 4. Especially since 4 has very few repeat voice actors compared to the last few Bethesda games - generic NPCs have repeating voices, but the vast majority of unique NPCs have their own unique voice.
(and again, comparing a good line from one game with a bad line from another is pointless)
You don't like Danse, Hancock, Deacon, Valentine, McCready, Piper, Cait, Codsworth, Father, Maxson? You don't like anyone at all? I find all these characters pretty awesome in their own way. I think the followers are definitely a step up from Fallout 3, I mean I liked Charon but the others were a bit flat to me. However I don't like any of the new followers to the extent that I like Boone.
Edit: Unless of course you meant just the npcs, if that's the case then if you get the John Marston looking dude with the deep voice, put him in suspenders and slacks, give him a bandanna and make him your weapons dealer, he is pretty likable at that point.
As someone who has been critical of Beth and their handling of Skyrim's atrocious writing and quest design, I can honestly tell you that IMO, Fallout 4 is a step up in this regard. It is, by no means, fantastic, but a definite improvement over TES V.
The dialogue wheel, however...
I can take or leave the voiced protagonist, but if they decide to use it again, I sure as hell hope they use a better voice actor this time. There are times where the voice acting for the pc is downright cringe worthy.
Overall, Fallout 4 isn't as bad as some people would have you believe. That said, I do miss skills, and the skill checks that go with them, but on the other hand, people had been asking for SPECIAL to actually mean something for the next Fallout, and now that's what we've got. I only wish that it hadn't come at the cost of skills.
I really miss Fallout 3. I never got tired of playing it and NV. Sad thing is, they just didn't work right on the PS3. That's why I am always posting that I would be more than willing to pay for F3 and NV w/DLC all over again if they would port it to the PS4 using Fallout 4's updated engine so they actually worked.
F3 and NV are my all time favorite games even as hard as they were to play on the PS3. F4 is great, stable, beautiful, but there's still no comparison in my opinion. It's not always about pretty graphics. If it were, I would get rid of my 286 rig in the basemant that I regularly fire up and play all the old 2D side-scroller's on. Monster Bash, Commander Keen, and so many others.
I double dare you to make Marcy Long likeable.
