I did a ~60 hour playthrough and completed every quest I could find without a guide. I didn't 100% the game or collect all of the possible loot, but I came fairly close. I enjoyed most things about the game, though I do wish more choices from previous games mattered. Anyway, here's my rambling thoughts on it!
The combat is very different, but after a bit I really started to enjoy it (I did play as a mage, idk what the other classes feel like to play as I have not gone back for a replay yet).
As for the dialogue, it felt very Dragon Age to me, though I mostly choose the sarcastic options (purple Hawke is my favorite). I didn't find it particularly bland, same with the voice acting. Sure, the dialogue writing isn't Baldur's Gate 3 good, but I didn't think it was bad either. It really reminded me a lot of DA1, especially after jumping right into a DA1 play after I beat it.
There's one kinda mediocre scene regarding one of the character's queerness (pushups lol) but I didn't hate it, and as a trans person myself, all of the queer focused scenes were very believable. People go "oh my god they're beating us over the head with queerness", which like, yeah they are, because that's literally how it can go in real life with people who are refusing to acknowledge or accept your identity.
The amount of lore that gets revealed made going back to the first 3 really interesting (I did a fresh playthrough of each but didn't quite finish Inquisition as I got distracted by Pathfinder Wrath of the Righteous)!
It also might help that I romanced Solas in DAI several times, and really enjoyed getting more of him (even if he made me angry at him a lot in this one).
It makes me think of Enterprise, where they don't have replicators but they do have protein resequencers, which can take waste matter and convert it into useful things, but they can't do energy to matter conversion yet.
