Review of Lord El-Melloi II's Case Files: Rail Zeppelin Grace Note - A Grave Keeper, a Cat, and a Mage

So, here's my review, before writing this, i've watched Fate/Zero, i've played fate grand order(here i'm talking reading his servant profile and playing through Fate/accel zero order) so i know additional background story about MC and his relations to referenced characters so you know- i can give a pretty decent evaluation of the story. Story: 6 i'm giving it a 6 because although Fate tends to be pretty well set with story and lore etc, this show seems to not show that much continuity yet, as a standalone episode it had a pretty nice plot and it's nice to see our boi Waver do his thing inthe clock tower for once, but i fear it'll become repetitive later on.
Art: 7
it's alright, i wouldn't call it foolproof but i liked how gray looked a lot and Waver, well he looks like waver... the people doesn't look completely dead inside and specifically the shadow shown later in the episode looked believable enough. the cars looked acceptable.
Sound: 8
nothing wrong here tbh, i would rate it higher if there was anything completely outstanding in regards to the sound, in fact it was just what i expected and i'm completely fine with that.
Character: 9
the characters really require you to have watched at least enough of fate/zero to know who Lord El-Melloi or Waver is because most of their backstory comes from there. but if you have watched that and knows how great a character he is you will understand how much i love waver as a character. I personally was a little disappointed that we didn't see more of him than we did back then.
gray is cool as hell imo i really look forward to seeing her character pan out, and why she is there etc.
those two kids, i really hated them during the first half of the episode but later on, when i saw their determination i grew to look past that as well.
Enjoyment: 10
this is a little biased like the other ratings actually but then again as a fate fan i really always loves to get a laugh out of an anime, and i got a laugh every time i saw waver be his usual "trying to be good at his thing but still fails" self.
overall: 8
it's decent, i'll say this now, the story doesn't seem so compelling as of now which i fear might actually be this series downfall because as my animu knowledge goes this has the potential to end in a repetitive format towards the middle of the series. but i think just because of the characters i'll end up seeing past that and enjoying the characters instead.
