It's too bad that this series was not able to do better, it had a talented cast, large EFX budget, a catchy (and once popular) premise, etc. The weak point was the writing, and it showed in episode after episode, although there was an improvement late in S2.
The problem was, the human resistance (the incorrectly named "Fifth Column") was disorganized and ineffective. Frankly, most episodes it seemed like amateur hour with these folks. Considering how inept the humans were written, I'm not surprised one bit that the Vs stomped all over them. Frankly it got to the point where I felt they deserved it, considering the numerous times their futile attempts to oppose the Vs fell apart. They never seemed to have a backup plan, trusted the wrong people, and were caught or tricked way too easily.
It was neat to have Jane Badler back though, but seriously why cage her in a dungeon the whole season, then kill her off just as she gets out? The whole thing was ridiculous, and while the season/series finale was shocking, it was also even more disastrously plotted than the preceding episodes (Really? Trust Lisa to kill her own Mother, and with no backup plan?). Earth: Final Conflict had a more effective Resistance than these guys (the ret-conned "Project Aries" nonewithstanding).
Hopefully next time a genre show of similar scope appears on a broadcast network, it will be more intelligently written. Frankly the rebooted V was not as good as the NBC miniseries, despite the resources it had going for it. Hopefully the talented cast can find more fulfilling roles.
