As far as no communications, why would there be? You can have a ongoing story where the audience sees both side of the war, Human and Romulan, without the participants talking to each other. In the second world war the allies and the axis navies typically did chat each other up as they went into battle.
One major difference from the Dominion War could be to write the Romulans as having a legitimate reason to engage in warfare with Earth other than they're evil, or paranoid, or crazy, or seeking revenge, or a "warrior people."
Actually, there was nothing wrong with the Romulan reasoning for going to War. They were an expansionist militaristic society, and all of a sudden, there was this new kid on the block (Coalition of Planets) which had the potential to spread through the quadrant like cancer, threatening their expansionist ambitions. It's only logical that they wanted to stop this new alliance before it grew too big and powerful.
The no communication thing was tolerable to a degree. What I find inconceivable is that in all those years of fighting, Earth's forces newer captured a single POW, or ran into a single dead Romulan soldier.
I vaguely remember a passage in which the Daedalus class bridge was described as looking intentionally "retro" or something, and this was justified by Starfleet's need to make those ships as low-tech as possible... This was obviously meant to reconcile the design discrepancies between ENT and TOS, which was silly and unnecessary, considering we already have the USS Kelvin, a post-ENT / pre-TOS Prime Universe (canon!) starship that looks awesomely futuristic and nothing on it looks like it was made in the sixties.
Come to think of it, this would, in "in-universe" terms, mean that the paradigm shift in Starfleet interior design (the "retro" trend) came AFTER 2233, but only in the Prime Universe (because the the designers responsible for it got killed by Nero
