Flash Forward! I loved this show and nobody else seems to have watched it, which was probably why it never got a second season WHICH MADE ME RAGE SO HARD! EUGH!
Ahem.
Firefly I agree with, of course. I also wish that Friends was still around but I did like the way it ended and I think that 10 years was kind of perfect for them. There is always binge watching online :D
in terms of animated stuff? Soul Eater, but by the sense that I wanted a sorta "Brotherhood" like treatment for it. Deadman Wonderland too, since it had no fucking ending -_-.
as for Live Action? Firefly only comes to mind, and it's been stated many times. Maybe This is England 88? i really can't think at the moment.
