Torchwood season 4 (Miracle day) Review

Hey the Season finale of Torchwoods 4th season came and went last week so here is my review of what started slow and lagged and ended ok enough. I will start by saying they turned the Captain Jack gay knob all the WAY up with 2 sex scenes one gratuitous(dude he picks up in a bar) the other very plot specific(guy who ends up having him mutilated). The story was something happens where people are unable to die which means that the system becomes taxed due to no one dying but people still being born. I do not want to get into the meat of this as its pretty dense and goes to some weird places. Long story short torchwood figures out through dragging shit out that Jacks immortal blood poured into holes in the earth which set the lifespan at forever. This was played out over 10 pretty dragged out episodes which ended pretty ok. My main issue with the end which is my issue with Dr Who is that the main plot devices(regeneration and jacks immortality) are being treated very blase and that is bothering me. Some devices should be protected and left alone as they are the linchpin of the whole series. I mean what does treating his immorality as something that can be passed around like a cheap flask of booze? The new people that were added to the team sucked especially the one dude who survived and is now immortal(see last sentence) he was insufferable. The benefits to the season was the fact that despite being on stars in the USA they saved some of the dour welsh aesthetic that Torchwood is known for. I also liked despite feeling like the story dragged in the middle the wrapped things up pretty swiftly and not many lose ends to feel cheated with. I hear they are going to do a season 5 which I am kind of hopeful figuring that they have a year of working with Starz and in the Usa giving them a good oppertunity to build on this years success.
