I just caught up on all five episodes. First off I'll just say that's it's good we have a rule about new shows and not judging it by the first episode!!
The first episode was awful, really bad. I agree with you Bala, it was arranged badly. I actually think the second episode was better as a "pilot" than the first.
That said, I really like the premise of this show. Plus, so what if Echo is the hero each episode, she is the man character. There is always a hero. I do agree that it would be nice to see a little more with the other actives, they are just a bit boring at the moment.
I also can't wait to see Alpha or what his deal is.
It's good that after each wipe, Echo retains a little of what happened. As time progresses, she's going to build up a picture of what is going on.
