Spoiler alert.
Glasslip is an anime that takes place during a summer about a group of friends in high school. A transfer student, Kakeru, moves to the town in the first episode and starts to make friends with the main character, Touko. Unfortunately, that's pretty much all there is to say about this anime. Nothing interesting happens. At all.
To see where everything goes wrong with this garbage, let's first consider the characters, and then the story:
Touko is the main character of this anime, and she's a usually cheerful girl who has feelings for Kakeru, and she experiences some sorts of visions sometimes. That's all there is to say about her. She's a profoundly uninteresting character.
Kakeru is a "mysterious" and cold student who also has visions and likes Touko. The most notable thing about him is that he's a schizophrenic who sees other versions of himself. He could be a very interesting character, but the writers never took the chance to explore his past and develop him very well.
Yanagi is Touko's friend who takes dance classes and has a crush on her step-brother Yukinari. She seems cheerful most of the time. I have nothing else to say about this boring character.
Yukinari is Yanagi's step-brother who likes to run and has a crush on Touko. He ends up punching Kakeru simply because Kakeru asked him if Yanagi confessed to him. In real life, you'd think he's justified in being angry at Kakeru for taking away his crush, but if you watch the scene, it's just so out of place and robotic that it doesn't really make any sense at all.
Sachi is a frail girl who has a lesbian crush on Touko and a crush on a dude named Hiro. She doesn't like Kakeru and plots to separate him from Touko. But she doesn't really do anything unfortunately.
Hiro is a guy who always smiles and has a crush on Sachi. To get Sachi's attention, he reads books. That's all I have to say about him.
Jonathan is a chicken who lives in the school. He seems to be a surprisingly intelligent chicken. The screen flashes to him after Kakeru and Touko kiss for the first time in episode 10, and for some reason he follows Touko around right before she kisses Kakeru.
I think the main problem with the characters is that every single character is like a robot with no depth whatsoever. You really can't think of anything else to say about them apart from that they're cheerful or cold, depending on the character, because they just have no depth. We seldom see any deep emotional reactions from any of the characters. The most emotionally charged scene, in which Yukinari punches Kakeru, is so robotic and strange that it seems completely out of place. It doesn't seem like any of these characters act like real people. If you pay attention to Yanagi jogging, even her breathing while they exercise sounds robotic and too much in rhythm.
Here's the main problem with the story. Nothing ever really happens. Here's a list of all the important events in every episode:
Episode 1: Kakeru moves to the town
Episode 2: Yukinari confesses to Touko
Episode 3: Nothing
Episode 4: Touko admits she likes Kakeru
Episode 5: Nothing
Episode 6: Yukinari punches Kakeru
Episode 7: Nothing
Episode 8: Yanagi walks around naked in her house for no reason other than fanservice, but it's a good scene. You get a full-frontal view (without nipples of course).
Episode 9: Nothing
Episode 10: Nothing
Episode 11: It's brought up that Kakeru is considering leaving the town. Nothing else of importance happens.
Episode 12: Touko experiences a day in alternate-reality-world. Nothing happens though.
Episode 13: It's not known if Kakeru decides to leave or not. The ending is open-ended. Apart from that, nothing.
It's a massive chore to watch each episode because the anime doesn't try to keep you interested at all. Every scene is meaningless and emotionless and pointless. I often have to spend every episode browsing my phone simply because I can't force myself to watch this anime without any form of stimulation.
Side-stories are completely and casually abandoned by the writers with no conclusion whatsoever. Yukinari's crush on Touko is a perfect example of this. You'd expect stuff like Yukinari punching Kakeru to have some importance in the story and cause some bad-blood between them for the episodes to come. Not at all! In this anime, Yukinari completely forgets that Touko exists half way through and this plot point is just abandoned by the writers. It's never of any importance again. Similarly, Sachi's quest to remove Kakeru from Touko's life due to a lesbian crush has almost no relevance to the story. It's mentioned only once or twice and never again. Another example of this is the visions that Touko has. We find out in episode 12 that they seem to involve an alternate reality. But what are they? Why do Touko and Kakeru have them? Who knows, it's never explained.
Glasslip is a boring, pathetic excuse for a romance anime that should be avoided. It's so boring that you can't even call it a "so bad it's good" anime. Because watching each episode is even more boring than counting blades of grass and watching paint dry on the wall: if there's nothing to laugh at while watching paint dry on the wall, why would you get any sort of enjoyment out of watching this garbage?
