I'm old enough to remember the original series and had hopes a remake would bring new ideas and fresh approaches to the concept. So far I've found the plot not particularly believable within it's context and I didn't really connect too much with most of the characters.
It seems they have gone for special effects and pretty people rather than characters, concepts like loyalty and statements about totalitarian government which the original series did rather well despite it's flaws.
I still have hopes the series will improve...generally it's getting more watchable compared to the Independence Day style pilot which didn't answer any important questions or build up the pace very well.
Let's see how it progresses - some great TV shows started out poor - this is just average and improving very very slightly.
