Who watched Torchwood all this week?

It was a very good 5 part But one of the biggest mistakes made was killing Ianto off one of the main members Big mistake indeed I have watched Torchwood since the first one in 2006 Tosh and owen were killed off last time around that was bad But Ianto is the main member next to captain jack also the relationship between the two I have heard a lot of angry fans across the net about the death of Ianto I would advise RTD the writer to bring him back somehow if their is gonna be a Series 4 next year Because for the majority of torchwood fans there is no point having another Series without Ianto What is the point of killing the main member and replacing them its won`t work  more
