I cannot easily describe with words the copied elements so that people who aren't from the same area of profession could understand. The only way to do that would be side by side comparison in a video.
I have mentioned earlier in this thread that their choreography is based on the same block of elements used in their first 3 or so videos. I will try to enumerate some of the elements below.
Their choreographer is mediocre and lacks imagination. He uses a lot of static elements to fill up space due to his incapability of finding elements to continue the choreography. His capabilities are even below Jungkook's, Hoseok's and Jimin's because they all got way to simple and average choreo for their solos.
The choreo in general is not at all difficult, in fact it is build in a typical "pop-let-me-fake-that-I-am-a-dancer" way. Meaning it would contain one element, such as a turning, stopped by a static moment, so that the interpreter doesn't loose his equilibrium. The only ones who can lift their feet somehow without looking embarrassing are Jimin, Hoseok, Jungkook (in this order).
Jimin is the best dancer out of all of them. He is the only one who is concentrated on dancing and not pulling a "cool/ angry face" , at least most of the time, I believe he enjoys it because he must know that dancing is the one element where the others aren't better as him, unlike the faces during dancing pulled by Jungkook (the most), Taehyung (second), Hoseok (third).
He (Jimin) has a fine and "clean" technique as well as expression and emotion in his dancing and his movements. By clean I mean that he doesn't encounter difficulties to go from element to element, which the rest have, including Hoseok, he doesn't have any slips, is full in control of his body.
Taehyung's dancing on the other side got worse, from the same timeline like his voice. He can do soft movements better than the rest, though. Like for ex their Dimple choreo. He is the most elegant one in the chorus and looks like his floating. But besides the ONE or two moments, he has no control over his body (same as with the voice - lack of practice) and looses on all songs at one point or another his balance from simple things.
Taehyung was the best dancer in the band until DNA.
Jungkook is boring, has absolutely zero emotion. His technique is shaky and often looks heavy. His posture is the worst to which I am going to switch.
What they all got in common as a first sign of trouble, except Jimin, is their tenure/body position. None of them are siting straight. I believe the term is hunched. When your shoulders and back aren't straight in dancing, without having a dancing reason behind it, it's a heavy sign of insecureness and lack of practice, as well as bad training.
Jimin, on the other side, even when their choreo is built to have the "hunched" look, which annoyingly is in almost all their videos, like 50% of the time, half of it based on static elements, half of it on unnecessary elements, he is the only one in the group who can execute the "hunched" look as a dance move and not like the rest.
"ON" - Fire, Idol, DNA, Not Today, Black Swan, Mic Drop
Black Swan - Fake Love, I'm Fine, Mic Drop, Airplane 2, Blood Sweat Tears
Boy With Love - I don't remember which video anymore, Jimin's entrance is from a different choreo/video, DNA, Fire, War of Hormone
Fire - Bulletproof, DNA, Not Today, Blood Sweat Tears
N.O and Bulletproof are basically the same thing. Not Today has elements from both of them together.
Fake Love is the one with one element that was new and has not been used again since then - Jungkook's ca 5 sec chorus part, the one when they push forward and he raises his shirt, but the beginning of the video is copied from a Hwarang scene.
On the other hand, what you see after those 5 seconds, are the same static elements used over and over again.
Boy with Love has the worst choreography, looks like a gay fitness training, but has the most new elements. I would estimate about 40%, but those 40% are the exact embarrassing elements that no one in dancing would use unless is a I don't know 80s macarena for boys.
Haven't watched Hoseok's chicken noodle soup, I've only seen Jungkook, Taehyung and Hoseok himself I believe posting a video of the chorus and besides of the chicken arm thing, the rest is the element from Fire, the ending of it, when they do something that looks like a spider move.
A little exemple to finish all this would be - Black Swan : they have an element at the beginning where Taehyung and Yoongi are reaching out the hands like in a ballet movement.
They do the same in Mic Drop.
One little thing and can be easily checked if you compare it with Mic Drop min approx 4:43 below
It's a very short moment, but one that an untrained eye can spot, which is why I gave it as an example.
In the same manner allmost their entire choreo collection is based on the same elements changed by switching the execution of the members and changing the hand movement.
Same element here at 0:32
The "Fire" element, or one of the elements used often in other choreos is the one starting at 3:50
