Baki is a wonderful brainchild. I haven't seen a series in so fucking long that tries to break the mold. In short, this anime is refreshing.
I normally don't take the time to write reviews. In fact, this is my first on this site, but I find this anime in particular is not getting the love it deserves.
Others on this site write huge, massively informed reviews, but I'd just like to throw in my two cents rather than get too wordy:
I have a huge soft spot for uniqueness; having consumes entertainment for so many years, things become predictable and boring when you do them by the book. Sure, Baki is not super proficient in the typical rating criteria used, but I'll be damned if Baki is considered "mediocre" just because it's story is less compelling than others, or the animation is not as fluid as possible, etc.
Baki is amazing; I've never felt so compelled to watch every fight in an action anime before. The choreography is so unique and inspired. The story is so nonlinear and piece-wise. The fun in this show is not found in the grand story arc like, say, attack on titan or My Hero Academia, it is in the moments. Ever episode has tons of distinguishing bits and characteristics that make you remember that episode forever.
If you're sick of action anime following the same fucking rules, the same fucking tropes, the same story format, then give Baki a real try. If you do like traditional anime styles, I'd recommend you try and loosen up and try to enjoy Baki as something new, like listening to a new genre of music for the first time.
P.S. If cannabis is legal where you are, try watching a couple episodes high. The action is so heavy and intense it makes you cringe and jump!
