Great to see the Servants finally in battle. I never fail to get struck by the sheer seriousness and professionalism of The Fourth Holy Grail War; everyone is basically coordinating and keeping up on tabs with each other, unlike F/SN.
Saber and Lancer's battle was an exciting watch; I was hoping for some epic music to pop in during the fight scene (OK, there was music, but not much, as if it was only to reinforce the suspense, the aura of the battle) but the movements of the Servants, such as Lancer flipping his spears here and there, were pretty eye-catching, so overall the battle scene was well done.
And Rider never fails to crack me up.
Plus, the epic music I was expecting played only during his arrival at Saber and Lancer's battleground.
Can't wait for the next episode. 8/10 (minus one for the wait :P)
