Just confirmed that the Fate/stay night 2014 series will cover the Unlimited Bladeworks route and there will also be a Heaven's Feel movie released later on. Whoa. That's a whole lot of Fating to come. Take a bow, ufotable. You deserve it.
Update after the '2nd season' has finished (and therefore the series.)
Previous comment still stands, but after a while the need for explanation for first-time watchers dwindles (as would be logical) so we end up with an amazing series with some massive animation skill and top of your chair action.
If you liked this series, also check:
Fate/Prototype (1 ep special about the original story, too bad this will never get a full story/series.)
Kara no Kyoukai/The Garden of sinners (Movie series)
And keep an eye open for (If ever released in the future):
Fate/Heavens Feel (confirmed for a movie.)
Fate/hollow ataraxia (sequel, no confirmation of a movie or TV show.)
As a big Fate fan I love to see the Fate routes back on screen. This series has a more 'stepping in' pace and is clearly aimed at both existing fans and viewers new to the franchise.
This makes a very balanced series, but it can be a bit repetitive and boring at times for the older fans.
Luckily Ufotable throws in everything they got and artwork is so amazing you don't really get the time to get bored.
