@CarmenSlamdiego apparently you are new to the Star Trek universe - DS9 could have ended after Season 4, and again after Season 5, then Season 6 & 7 breathed fresh life and storylines into DS9 - Voyager could have made it back to Earth in the 5th Season and again in the 6th Season - but it took another season to get back home, with a very uneventful finale that left open unanswered questions, whereas Enterprise ended prematurely with gaps never closed...
