Fate/stay night: Unlimited Blade Works is a remake of the original Fate/stay night anime but takes the Unlimited Blade Works approach. On this episode, Rin is living her usual school life and then summons a Servant. Later, they encounter some problems.
So I'm not familiar with the route that the series is heading to but seems to be better than the original. It's interesting to see Rin and Archer being focused on unlike in Fate/Stay night. Also the action is just great as usual. Other than that, I've been waiting so long for this remake to come out and it was simply worth the wait especially that the episode time was longer than average. Now how will Rin and Archer deal with the next Servant? Overall, awesome introduction and action.
Conclusion: Awesome introduction and action.
