The story was pretty cool, the actors a little less. But still everything apart. And btw there is 1 end. (No open end) There was room for 1 continuation
I have to agree with Dubst3p on this. The acting level really sucks. That's why the series was probably canceled after 3 episodes. Also, the script wasn't the best.
At first I thought, no, we're not going to continue with that., After my vacation I gave it a try and I have to say it's not disappointing. Now seen up to episode 9 and I'm curious about the last 3 parts.
Zero Hour has already been canceled and they are still looking to show the rest of the 13 episodes they bought this summer. See http://tvline.com/2013/03/01/zero-hour-cancelled-by-abc/
I thought this was a good series, if you like Dan Brown-esque stories you'll like this. It was canceled after a season but they have made a good end so if you want to see a short series with an exciting story, this is a must.
Sometimes you have high expectations of a series, like with Hannibal and sometimes not at all like with Zero Hour! Turns out the first mentioned is cringingly bad and Zero Hour which is a combination of Indiana Jones most Dan Brown is quite good!
