Alias is definitely one of the best television series ever made. Every episode has the quality of a movie, large attention to detail and superb plots.
The show explores the world of espionage and has non stop action with lots of heart-stopping situations and stunts. Jennifer Garner is sensational as Sydney Bristow with the many disguises she uses while on missions, and her strong new age character brings enormous sex appeal to the show.

Sloan is so evil yet very fascinating, and has such an important and interesting role in the overall scheme of the best plots. Another bad guy is Julian Sark, played by David Anders who is absolutely outstanding
