I only had two real problems with the series:
- The cool echoing effect was gone from the Visitors' voices.
Which was a symptom of the lower budget of the series as opposed to the miniseries. Though it also created the story opportunity for having Visitors pass for human on occasion.
- Martin/Philip. Unless the look of a Visitor's human disguise is somehow 'tied' to his/her actual reptilian appearance (which is not a bad idea, really), there is no way that anyone could immediately recognize Philip as Martin's twin brother. Any Visitor could be the one under that mask.
Ahh, but only a twin would have the same voice, right?
