I very much enjoyed watching season 2. I felt it had good balance between sci-fi and drama to keep the story interesting and entertaining to watch. Am not a movie critic, just a fan, so don't ask me if the acting or production was award worthy. All I know is I thoroughly enjoyed watching this and would still re-watch it and still be very entertained. I was worried how the story would go after the end of season 1 cause now they had to show us the alien threat and how they actually looked like. Let's be honest some good sci-fi shows suffer from cheap alien effects but after watching this I was very very satisfied. It had all the intriguing elements I like in a good sci-fi series, including the other life forms.
