Another season might have spared us the finale that dare not speak its name
There was nothing wrong with the Terra Prime story line, the episode that aired afterwards was a TNG episode.
As for ENT winning the poll hardly suprising saying that many say it was just getting good when it was cancelled.
TNG carried on into movies, and DSN and VOY ended their main stories in their respective season finalé's.
It was either going to be TOS or ENT that won.
