Killjoys season 4 has come to a close on Syfy, and with the fifth season already guaranteed as the show’s last, the build-up has been pretty massive. The show has inexplicably improved each year just when fans think it couldn’t get any better, and the scope of the series has broadened to include a wider look at the J sector, the invading Hullen, and the mysterious Lady of the green.
