These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Gildorome is, perhaps the single most depraved character in the series. While Death Gaia and Helmut are insane, their way of thinking is extremely straightforward. Shapiro, himself preferred his knowledge of earth geography and his battle tactics to take down the Cyber Beast Force. Gildorome? No, instead of using conventional methods, he preferred psychological methods, such as using a Lotus-Eater Machine to hypnotize a whole town to kill them when they can't even fight back. In the long run, his methods caused the highest number of innocent victims in the most brutal way possible.
Hontou no Kiss, in particular the remixed version in Super Robot Wars GC. The fact that its considered one of the best, if not THE best remix in SRW says something.
Hilarious in Hindsight: The fact that Shapiro constantly reminds you that he is the man destined to be a god becomes more hilarious, when you notice that he is voiced by Norio Wakamoto. Bonus points in that this is his first Major Villain role.
Seasonal Rot: Some fans dislike the Blazing Epilogue OVA, for a number of reasons.
They Wasted a Perfectly Good Character: Frankenstein. The only character from Muge Zorbados Faction that actually experienced being cared by a human and pulled a sort of Heel-Face Turn only to be killed off in a Heroic Sacrifice. Admitably he goes against the whole point of the show, but that did not stop him from being an interesting character who can be used for some developments such as the first step towards peace, something that the team mentioned.
