Not sure which bad guy you are talking about, but did you recognize Max? After watching the first episode I had to google the cast as I knew he looked really familiar, but couldn't place him. Same with the lady ambassador.
Solid Meh for me this season and I hated the ending, although I figured there wouldn't be a solid ending just because of the situation they were in.
Started watching Daybreak on Netflix, which actually turned out to be better than we thought, although it isn't for everybody. What's funny, the wife and I binged watched a show we hadn't ever seen even though it came out in 2013, Under the Dome. One of the main characters in that is also on the show Daybreak, surprised he is still playing a teenager.
