Alias combines thriller, mystery, action, romance and drama. After the pilot I already knew that that was not going to be like anything I had ever seen before in my life. It was extremely exciting to see Sydney Bristow work as a double agent for the CIA and SD-6 and later for the black-ops division APO. But the great thing was that the stories were not just about agencies, but it had the underlying story of Milo Rambaldi, a fifteenth century prophet, who made prophecies about Sydney and other members of her family. Next to the action was also a very human part. There was the difficult relationship between Syd and her father Jack Bristow as well as the love story with her handler Michael Vaughn that had to face a lot of obstacles. Also very hard to handle was the thing with her mother, who killed Vaughn's father and her sister Nadia she never knew she had.
This was a show where you had to watch every episode. Otherwise you wouldn't have been able to follow. But that was no problem since you couldn't stop, even if you wanted to! And it had some of the best cliffhangers ever!
