Could have been better...
25 March 2012 | by (Argentina) – See all my reviews

I liked this two parter, though I liked Pandora better. This closing is also fast paced, keeps the twists, but stretches a bit too much. The plot was promising and complicated, but it kind of falls apart when it all comes down to a single character. The one traitor is the person who designed a devilish plot to unleash WW3, did all the killings, was on everyone's back all the time without raising anyone's suspicions, ...well it is just too much.

It was entertaining and we all wanted to see how it ended, but the excess of computer tech, geeky stuff, magical databases, the good guy suddenly revealed as the incredibly evil bad guy, the hidden shooter who saves the hero at the last minute, the life changing confession that is left incomplete because the character dies...this all makes it a bit tedious.

I think the plot could have been handled much better and the Sophia character that resembled Beckett's situation with Castle could have been exploited way more.
