The first season was pretty amazing. Plenty of intrigue, action, personable characters, varied motivations. And the overall storyline was solid, if not quite living up to the potential it seemed to have. 7.5 or even 8 out of 10 for me.
Unfortunately, the second season was a complete mess. Some characters made decisions that ignored either their character or the rest of the story (eg. Ignoring friendships and trust that had built up in the first season); there were multiple plot 'twists' that broke from the rest of the story, seemingly thrown in, unplanned, for the sake of a twist rather than plot development; and the story doesn't even have an ending.
