First thing's first, Hypnosis Mic has what is probably the best usage of CG that I've seen in a 2D anime. The transitions to CG animation feel like you're jumping from the show to a music video, which is a perfect mood for these sequences that keeps the switch from feeling jarring. On top of that a lot of the music just slaps, not just the rap itself but even the background music goes in hard sometimes.
What really makes this a fantastic anime though is just that it's really fun. I'm personally not a fan of yaoi-centric shows like Free or Yuri on Ice, and I see a lot of the criticism against Hypnosis Mic talking about how it appeals to fujoshi similar to those series... and I just don't get that critique at all. This isn't about male-oriented fanservice, this is a show about guys bein' dudes and spittin' some hot fire. For better or for worse, I think HypMic is something truly special.
