the 2nd season of Index is a lot more better compared to the 1st season...the characters are a lot more interesting and the plot is a lot more solid. only a few anime tackle the issue between science and religion as well as Index though some might find the characters a bit extreme but i personally find the idea to be refreshing! We have battle nuns, derange bishops and other religious characters who isn't afraid to sacrifice anyone in the name of religion plus we have some interesting items like the Book of Law & Peter's Cross as well as some freakishly insane magic! The action isn't in par with Bleach or Onepice but it's worth the watch! While Railgun tackles the dark side of science Index has shown how Religion can be as dark and unforgiving as well! Fan-service aside this is one of the best anime i have seen to date and if you are interested to see a different side of sci-fi and fantasy this one anime you should definitely watch! Hope season3 isn't too far behind!
