they did it because smallville had a 2 hour series finale episode and took up supernatural's
timeslot this week.
ahh thanks.. dont watch that so didnt even cross my mind..
@scifi3001 wouldnt class s6/7 as a reboot, more like a second chapter.. if there was a year or two
between them in real time, i would use the term, but not otherwise. it's still the same show, with the same
cast and overall premise. yes, some of the backroom has changed, but very few shows run for 6 years
without someone dropping out.
