There's some speculation ongoing about 2nd season and apparently the producers said something along the line of "we'll see" but honestly I don't see the point. Yea an epilogue episode would have been nice but an entire season is massively redundant. What would we be getting, more prequel or a court drama?
I don't get it why whenever something good with a closed, finished storyline appears - a movie, a TV series, a game or an episodic game season - almost immediately people start calling for a sequel. Can't we just leave good things be? And then we complain when things get milked to death.
