I liked the premiere a little more than the Fate/Zero premiere, but it was still kind of boring and unnecessary. Graceless exposition is replaced with... Something, I'm not even sure what part of that episode took up the 40 minutes, but I didn't really feel like I watched two episodes' worth of content. Will keep watching, do not expect to love.
Maybe I missed something, or maybe this will be explained later, but did they change the rules of how the game works? Why do the masters get random servants now? I thought they had to find an artifact that belonged to their servant in order to summon them. How does that even work?
