I wonder how much thought was really put into what to do with the Romulan War. Especially since they started the show in 2151. I wonder if B&B intended to shorten the length of the war, which was conjectural at that time anyway, so that it didn't consume the show or that it wouldn't end on a cliffhanger. Or maybe it could've ended in the midst of the war which would serve as a springboard to movies. Interesting time to start the series in any event.
I do think there was a lot of good in ENT, but like others have said, they wasted or misused a lot of it. Or ignored it until it was too late. I wish they had had in mind to flesh out the Tellarites, Orions, Tholians, and Andorians (more than they did) because there was little that had been done with them since TOS. It could've been something that might have interested both new and old fans. Building up the Orions would've been more interesting and tied into the prequel concept moreso than making up the Suliban for example.
