Yeah it is such a crime that the series got killed off. I think they used up the rest of the story though in the film so thats our lot - not to mention that they killed a couple of key characters. At least we got all the answers that were lingering from the series although I would have liked to see more of the chaps with the blue hands.
On the upside, you can see the whole series and cap it off with the film in one stoned rainy day

haven't seen Doom yet as I don't really know any old school gameheads here
