UPN didn't want Year of Hell to last a season.
UPN wanted Temporal Cold War.
I wouldn't say they wanted the Temporal Cold War, it was just the only way to fit the execs demand for stuff that was even more in the future than DS9/VOY.
But yeah, when I wrote an article about 10 awesome unproduced Trek projects, I lumped Braga's Year of Hell season and his ENT S1 together at the #1 slot. If this interview had been released earlier, I would've ended the article with it. It just changes all your perceptions of the Berman and Braga era.
