This show was running on TV in my country. And when I turned to the TV channel at night where the show was running I turned it off - I got to say, that I never watched this. Why? I found the plot sooo stupid. Just another show with an agent, and the agent is solving different problems and cases in each episode.

Well. In some way this might be true, but there is more behind that. A bigger story.

Now I am in the second season and I gonna say, that the story develops good. Sometimes I get really surprised about the change of courses of the characters behaviour.

If you like action, technical agent gimmicks and action scenes you might consider watching this show. J.J. Abrams was the producer of this show, so you also get a mystery factor in it - but I do not want to spoiler that.
The characters are developing great during the show - but I gotta say that there are some "over-subscribed" chars... The technic-guy for example. When you see him, you know what I mean.

What I also don't like is, that in each episode there are 1 - 2 action scenes, and then the part where there is the emotional/private stuff for the characters. Thats getting boring, because you already know: "Oh action scenes are over - okay now she's talking to her dad, tears ladidaldida". ^^

If you are into spy stuff, you might try The Americans which I like far more.

I think Alias is good. 7/10.
