I haven't seen any of the new ones yet. Because the BBC dicked about when they originally aired years ago and never told you when it was the end of the season or when it was coming back, and it just randomly disappeared, I think I have only ever seen up to season 6. I am working my way through them properly atm and have just started season 4 and am looking forward to catching up with the newer ones.
As an fyi though, this may be the last season because Gillian Anderson won't be coming back.
