I just find it a bit boring for the same publisher, just months apart to, gives two different accounts of the formation of the Klingon-Romulan Alliance. That comes across to me as a lack of imagination, to mine the same idea twice so soon!
It's not really fair to call it a lack of imagination, because the ideas would've come from two different people or teams. Was it due to a "lack of imagination" that both Bill Leisner and Dayton Ward submitted Lucsly & Dulmur stories to
Strange New Worlds II? No, it was just that two different writers independently decided to explore that subject. And the editor accepted them both because they were both deemed worthy of inclusion, and it wouldn't have been fair to scuttle one of them just because of the subject matter.
In this case, I believe the two "accounts" you're talking about are the one in D. C. Fontana's
The Enterprise Experiment and the one in John Byrne's Romulan miniseries. Now, really -- we're talking about
D. C. Fontana and John Byrne. These are people that are going to be given the freedom to tell whatever stories they want to tell. If they both independently, coincidentally decided to do stories that happened to touch on the Klingon-Romulan alliance, then so be it. If they want to tell stories that are out of continuity with other comics, so be it. Hell, Byrne's Romulan saga even contradicts
canon, by claiming there was a Klingon emperor in the 2260s. And yet they let him get away with that, because he's John Byrne.
