Yeah, I've never honestly believed that the B&B team brought about the downfall of Trek. Everything I've seen, I've pretty much enjoyed. Loving the hell out of Enterprise Seasons 3 and 4, even though I know that Manny Coto is somewhat responsible for giving Enterprise a bit of palatability that folks felt was missing from Enterprise.
In truth, fanboys were just looking for someone to blame, other than themselves, for ruining Trek. So their scapegoats were Brannon and Braga.
Just the same now as folks blame JJ Abrams for ruining Trek.
Hell, for all we knew, Roddenberry ruined Trek from the get go.
