Damn those yanks and their tv *shakes fist*
I completely understand though, i've been watching NCIS and they only released season 6 on DVD last year and the US is mid-way through showing Season 8. As for Supernatural, i only came across it by accident and still catching up with the series. Still miles behind everyone else. Same with True Blood, got the first season blu ray set but never fully finished watching it. Good show but just too many other good shows to watch.
Rest assured we get to have our own back on them with BBC productions. They have to wait a while for episodes of Top Gear, Doctor Who, QI, Being Human and other shows. So its not completely one way.
