Justice League Unlimited - Season 4 is one of the best tv series released in 2005. I will grant that my expectations were very low before seeing it. The tv series industry, can't really boast with a big number of tv series better than Justice League Unlimited - Season 4. However, this genre may boast of one of the larger number of popular titles. The storyline is really good, the pacing is great, and the actors gave great performances. I can't say that I'm a big fan of Action, but I liked it!.
