If the series had been allowed to develop along the course it had been I'm absolutely positive the producers/directors had a long term plan and vision with Casey...unfortunately the backlash meant that all those complaining about "Casey Jones" being female never got to find out that wasn't actually Casey Jones at all (as it seems here)...
They did a few things like that in the series, misdirection and subterfuge...
Happy that whatever small Rise fandom there is, we got a bit of a send off in the form of the movie.
I just hope this comes to UK Netflix. No sign of Season 1 in the UK...
