@jespah,
To be honest, I still haven't seen the last season of Enterprise. Part of which, I was kind of influenced by the negative criticism held against that final season.
I really enjoyed the other seasons but not enough to tackle ... what I dreaded to be a possible broken, anticlimactic final season. That said, the fact that the final season consists of a time travelling story arc (or so I read) does possible spoilers cause a dangerous time paradox or am I overthinking it?
