Tim Bradley told Digital Spy: "We do have a little more character development this series, and we do have some very dramatic plot points and a different grouping of characters. So the energy's there and we'll have a lot more story."
"It's easy to get a bit stale," continued Bradley. "A creature will come through and terrify people, then either it gets shot, lured or kicked back through an anomaly. So we're changing that a bit."
"In each episode we've tried to vary the creatures, so some will be different from those you've seen before," he added.
