Warning, this review will contain minor spoilers for the Anime.
I'm a Spider So What, is an anime with a very interesting story, and from what I can tell rather interesting characters, but with an anime adaptation that is so bad, that had I not been hooked to the story, I would have instantly dropped the series.
Unfortunately, while the story is very interesting, the author picked studio Millepensee to bring his anime to light, and for those of you who are unaware, studio Millepensee is the same studio which was responsible for Berkserk's first and second season adaptations. So from the start, I instantly feared the worst for this anime, and the worst happened.
From horrendous CGI, to animation in the later half of the anime which was so poorly made, that I wouldn't even be exaggerating if I said that my dog could probably animate better than that. (And no, I know animating is hard, but trust me, you have no idea how poor the animations is in the later half of the anime. I will however, give them props for the animation at the start of the anime.)
In terms of overall Aesthetics. it starts off at a fairy nice light, nothing visually astounding, but not bad either, so I would say overall mediocre. However, as the anime progresses, there is less and less detail placed into the artstyle, which results in the anime being visually painful to look at.
In terms of animation. This was where the studio adapting the anime mainly failed at producing. While at the start the animation was decent enough, it was absolutely horrid at the end. Furthermore, this anime frequently switches between 2D and 3D, without trying to smoothly transfer between the two, which results in pretty weird scenes. Especially considering that some scenes have both 3D and 2D characters next to each other at the same time.
Adding onto this, 3D is not necessarily a bad thing, I have seen several 3D anime which manage to use 3D well. There are also western cartoons such as "The Dragon Prince", which I absolutely love, which is entirely in 3D. However, this anime fails in the 3D aspect. Fights are poorly animated, especially at the end, and the anime never takes advantage of the 3D models to make stunning camera movements or anything of the like.
In terms of voice acting, this really depends on you, I personally really enjoy the voice actress of the main character, so do most of my friends. However, I know that the majority of the community dislikes her voice acting, as such I shall not comment on this aspect.
Character 6/10:
Similarly to what I mentioned inside sound, the characters in this anime are really hit or miss, meaning you either like them a lot, or else you hate them. Unfortunately though, apart from a few main characters and side characters, I feel that some of the major cast have rather bland characters. However, I didn't find any of them to be annoying, or too bland, as such I believe a score of 6 is justifiable.
Enjoyment 6/10:
I overall enjoyed watching this anime. However, to be frankly honest, it wasn't really the anime I enjoyed, but rather the story that was portrayed within the anime. I will definitely not watch any second season. However, I do plan on grabbing the light novel and reading it through to see the story that got me hooked into this anime.
Overall 6.3/10:
The Anime Studio honestly ruined the adaptation of the light novel. While the anime is still pretty watchable, and as long as you like the story, you should remain entertained. I would highly recommend reading the Light Novel instead of watching this anime.
