The same events leading up to the Romulan war could've been told almost as easily inserting another character besides Trip IMO.
Hmm, but would it really be an "ENTERPRISE" story without Trip in it?
After all, he was, to my understanding, by far the most popular character on the show.
Yes, it could be an Enterprise story without Trip IMO. Though it wasn't quite an ensemble cast, there were still several main cast members besides Trip to choose from. From my recollection, both Hoshi and Travis have gotten the spotlight in recent novels and they didn't stop being considered "Enterprise" because of it.
Trip by far became the favorite of the writers and since he got the most development, coupled with Trinnear's engaging portrayal, the favorite of many fans. I'm not sure if he was the most popular though. I guess we would have to do a poll. I think a lot of people liked T'Pol and Shran too. And there are some Archer fans out there as well. And small pockets of Hoshi, Travis, Reed, and Phlox fans. Without the Trip crutch it forces the writers to flesh out the rest of the characters, and for the most part I liked Martin and Mangels work with Archer, T'Pol, and Travis in LFM, TGTMD and Kobyashi Maru. It might even be better without Trip sucking up most of the storyline oxygen.
Despite the suckitude of TATV, it might have been a braver choice to write books without Trip-the tentpole/franchise character-instead. I think T'Pol, with her background in intelligence and being a Vulcan of course could've done the same job Trip did without the convulted backstory, with a little tweaking of the storyline.
I've enjoyed the Romulan intrigue in both TGTMD and Kobayashi Maru. However, the buildup to the Romulan War wasn't what I expected-and not in a good way. That being said, I'm curious to read the Romulan War book coming out regardless.
