Unlike Chag, I believe the enjoyment of this series comes not from the preference of Super Robot animes (come on, this is way way better plot-wise than most of the classic TV shows - you don't just diss and rate a show against it's genre) but rather more on how much you know and love the Getter Robo series. As a person who only sporadically saw Getter Robo and never read the manga especially it's version of Shin Getter Robo (which I've heard was way better), what makes this OVA stand out was that it actually implemented many of the elements from Gunbuster which is oneof my favorite anime.

The overall events never matched up to how Gunbuster was but at the same time the fact that this was a classic Super Robot series with a very conclusive respectful "death" of the original iconic three speaks volumes for why this is an outstanding anime.

In the end, Shin Getter Robo is not for everyone even including hardcore Super Robot fans but for me, it is certainly among the most epic series out there. The way the timeline shifts, the character evolves, the annoyances of typical characters toned down...I stick to what I said in my original sentence. Sometimes there are shows where you can criticize the show because of it's genre but sometimes there are shows that are presented in such a way that it's like criticizing Batman for wearing his underwear outside which is different from criticizing his having nipples.

Shin Getter Robo has many parallels to the dark iteration of Batman. What many non-fans or even hardcore fans may see as psychotic poorly written turn of events for violence's sake, I see as near-perfectly shifting cookie cutter heroes into charismatic anti-heroes that would strongly appeal to even general classic Super Robot fans who didn't watch the original series.
