No need to completely discard what we all know, there are enough 'blank' spots to fill pllenty of series. The main trouble I think is that the modern writers fall to easily into 'plot device' story lines, like holodecks or visitors from the future, for conflict starting and resolution.
'Enterprise' for example, could do whole episodes based around setting up a colonoy, and never have to bother with 'aleins' of any kind, a good writer could create conflict among the colonists themselves, and maybe the fleet command, they don't need it to always be some alien or 'futurboy' who drives the story.
Another factor with B&B is they always miss a trick, when they can do cool stuff. When the ship left earth to begin this stupid Xindi story line for example, she was a year old. They could have repainted her white and given her an NCC-01 on her hull, as a tip of the hat to the old timers and a link to the future. No, not B&B, they want to jump to the 24th century and that stupid time cop idea they had.
They disgust me.
