The World is a Graveyard

So the other day I finished Torchwood, it was (of corse) super depressing. I'm not going to give anything away, but I just felt like with the ending it almost closed of Torchwood forever. I feel like if it was just Torchwood and there wasn't any Doctor Who where we already knew Jack's future then it would leave more hope for future episodes. Also with the ending state of the characters I feel like it wouldn't be the same if they continued it. No matter what I will always ship Jack and Ianto though.
