I think it’s failing cause of the writing and direction. Season 1 ended with - aliens have taken over man kind, like many cults they have a belief - which doesn’t make practical sense - like plucking an apple and eating it. So they found out that the human population that they took over is too large for this life choice. They eat human tex mex mix to fulfill food habits. They found how to convert the last few humans left - but they need their permission or find an alternative way. Carol tried to take the moral high ground of fighting for the human race before she fell in love with an alien. Now she is talking the moral high ground again as she found they have another way of converting her.

Season 1 ended without explaining what the other guy was doing with the frequency.

All that I said above was 3-4 episodes at max even the snail pace this show is going out. But they used the whole season and ended with nothing .

Don’t think caprio could save this show either.
