The end of V?

I've been quite enjoying the reimagined version of V but yesterdays episode was supposed to be the last.

The only issue there is so much was left open.
The Earth and most of its occupants were Blissed but Erica and the Project Ares cabal were safe and untouched leaving some resistance still left.

Apparently the pull-out shot that showed tons more ships arriving was supposed to let us know The Visitors had conquered Earth. My problem there is Bliss wears off and no self respecting human is going to sit on their hands and let a bunch of aliens take our planet.

They either have to make 1 final special to resolve the fates of ALL the characters or make season 3.
