Yes, I hope this will be something we see more often, and that other networks take note of. If you make your decisions at the right time and smartly, it doesn't cost you an arm and a leg to adapt to an early cancellation and at least let the writers and artists make the best out of the situation. Not alienating your viewers is a good move in the mid-term. I think that this grain of respect is something viewers deserve for tuning in every week.
As for the shows themselves, I'm not terribly surprised. 666 Park Avenue peaked my interest stylistically, but then it turned out to be incredibly cliché. Nothing we haven't seen in every Poltergeist clone, and I don't like effects and camera trickery glossing over plot holes. A charismatic Terry O'Quinn really was the only thing carrying the show. I liked Last Resort a bit more, especially its bold premise, but it got a bit too under-exciting for its own good too early on. These guys stole a U.S. submarine, invaded an island and declared it a sovereign, nuclear nation! So how are they calmly solving their petty islander squabbles with everyone seemingly forgetting what they've done, and what might happen next?
