I thought it was a good episode. I like Tom as a bad guy, even though he's still an awful actor.
I liked (sarcasm) Collier's explanation of why they have to keep the test underwraps:
Collier's point: If group A knows they are better than group B, group A will kill group B for being inferior, or Group B will kill Group A because they are jealous. I think the exact quote was "It's either inquisition or genocide."
Then he immediately reiterates how he needs everyone to take the shot so half of them will die and only people with 4400 abilities will remain.
Umm, how is that different from genocide?
Honestly, I don't see how anyone could look at this episode as THE episode that turned them off. There have been many many bad ones. At least this one advanced the plot a little.
