The animation in the show is so weird. I get the impression that there really aren't very many (or any) experienced animators who know about antics, slow in/slow out and so forth. They just boot up Flash or Harmony or whatever, feed in the key frames and let the machine do all the rest. So it all ends up really mechanical and abrupt looking.
I heard it was done by a small studio, and they have been improving the animation a little with each episode.
I'm not sure if animation got less horrible, or I just got used to the quality...
But yeah, you kinda need to get over the first episodes, they give the worst impression. Especially that very first scene of chasing...
Having just read it, I haven't seen any "phobic" or even "rude" contend regarding him. He's not much of antagonist,and he has his own struggles with his grandfather.
If anything, Ren's shown to be very superficial, swooning over him in a female outfit.
Edit: He seems to think that he's a woman (with a man's heart) until he does the genital surgery. This is horrible, transphobic, completely wrong and it just shows what cisgender (non-trans) people think of us.
