It's weird, it's like they've effectively killed off Torchwood itself (as we knew it anyway), with 3/4 of the team well dead
I'm thinking the idea they're using now is that TW can still exist and will carry on as long as Cap'n Jack is there and tied to the story somehow (as well as Gwen maybe), other members can come and go as can different plots
I preferred the 'proper' seasons of Torchwood though, it's a great point to say that the show can grow, adapt and be changed in which ever way the director wants buut changing it so much that it's nothing like the original Torchwood that gained all the fans, the show we all love is a bit so silly
Also some aliens need to feature again, soon
