A stand-alone TV movie really can't be an arc in the same sense
as a season of the show. So I can't really consider it "a year." A
year of story time equals one year of real time. That's the five year
arc, which refers to the *series*, to that specific one-to-one ratio.
The movie I've always considered to be a preface, or introduction...The
Hobbit, if you will, to The Lord of the Rings. If it were going to a
sixth year arc, then it should've covered a span of a year; but it only
covered a few days.
