Fate/Stay Night: Unlimited Blade Works 0
I'm a fan of the Fate series because for better or worse, I love the visuals of the characters. Shoot me all you want but I always loved the characters in KnK, F/SN, and F/Z. Having said that, this episode was an absolute scorgasm of visual glory that ufotable has to offer. I don't think there is any studio out there that can make a show look this damn good for a weekly tv anime series. None. Having said that, I felt like everything else about the episode didn't live up to my expectations of the show.
For instance, I found the lack of characters extremely obnoxious and the blocking of Shirou's face even more obnoxious. Let's hide shit just for the sake of. Piss off. I understand the intent of making a Rin-centric episode but I think it's done at the cost of introducing essential characters and showing how they actually relate to the overall plot. Whatever.
To further add to the problem I just didn't enjoy the lack of character dynamics. You are only introduced to Rin and Archer in all honesty. You only get to see their interactions and no one else's. I guess the one that comes the closest would be Rin and Sakura's but that's hinted at. Doesn't even scratch the surface.
I think the episode tried too hard to allude to something and really delve into something that really didn't need 30 minutes of delving into. Maybe I was just spoiled as to how spectacular the first episode of Fate/Zero. This episode just felt bland.
It's called episode 0 largely because of the complaints you listed. This isn't the actual story yet this is Rin's story,the actual story starts with episode 1 and the protagonist.
Also I don't mind that the blocking of Shirou's it does set the character apart in comparison to every other character Rin meets, because their all side characters, in comparison to the actual main character.
