Just to chime in with my own opinion. Personally I absolutely like the isometric view. For a party-based RPG, there is simply no better way to keep a good overview and keep everything under control. (Note that single-character, action RPGs are a different thing entirely.)
As for additional cinematics, I am also in the camp that prefers to let their own imagination fill in the blanks. For that reason, I am also not a fan of fully voiced dialogue. Give me a line or two to establish a characters voice, but then do not force me to suffer through 2nd-rate voice acting that only serves to slow dialogues down. But without full voice acting, close-ups of the speakers are pointless, IMO. Now larger and possibly animated NPC portraits OTOH would be a welcome improvement.
Pretty much the same goes for cinematics during combat. To me, any close-ups or a kill-cam would interrupt the flow of the battle too much. Constantly changing perspective between actions makes it harder to focus on the actual going-ons. I also don't need to see kills in gory details all the time. That soon gets old and boring and needlessly drags out battles that aren't exactly short anyway.
In brief, I'd rather have Larian invest their time and money into gameplay, story, quests, etc. instead of visual fluff. A pretty facade may hide shortcomings in gameplay for a time, but excellent gameplay can stand on its own. If graphics start to distract from the gameplay, something is not right.
