B'T X Neo is a great sequel to the original TV series. It not only has better writing but also offers an upgrade in the technical side of this animated series as a whole. About the writing, B'T X Neo is darker, grittier, with a more dramatic atmosphere, compared to the regular B'T X. I totally liked that change. It fits the overall tone of the later arcs and the climax itself. It also allows for a better portrayal of things that, sadly, were not present in the TV series, I mean many significant characters' backgrounds or motivations. The soundtrack has improved over the TV series. Thegreater variety of songs and their matching to the scenes they accompany makes the whole thing more comfortable and immersive to watch. Just like in B'T X's opening theme's case, Neo's opening theme is a total banger of a song. Not better than the previous one, but still awesome.

When it comes to art style and animation, the OVA series is also an improvement. Art style remains pretty much the same. It doesn't have drastic changes, but that's good. What felt underwhelming when watching the TV series was the animation. It was not bad, but not good either. Just average. Luckily, B'T X Neo has better animation in general. That also includes the direction and dynamism of both action scenes and more timid ones.

I thoroughly enjoyed this sequel. A brilliant conclusion to the show and a visible upgrade in many aspects of the prequel series. Sure, it is not without any cons and some things could've been done better, but for 14 episodes, I think B'T X Neo is packed with very decent content coated with well-done audiovisuals. In short, different types of shortcomings are covered by elements that are polished and simply properly made.
