YMMV / Go, Go, Loser Ranger!

• Arc Fatigue:
  • Some felt that the Bailong Exams (Chapters 17 to 50) overstayed its welcome. Particularly, the earlier portions where it centers around D and the colorless recruits taking on the exam to try to become colored rangers. It's not that it's a bad arc or anything, but more that D's quest to defeat the 5 Dragon Keeper Rangers is considered to be so much more interesting than a recruitment exam plotline that people just wanted the series to finally return to D's primary objective. Thus, the Blue Dragon Keeper getting involved in the last third of the arc from chapter 36 onward is viewed to be what saves the arc from being a slog the whole way through.
  • Lasting roughly the same amount of chapters as the above example, the Three Way Battle arc is seen as an exhausting one by many readers who think the manga is trying to include too many plot twists into a single arc, resulting in it becoming both very long and very plot heavy. From the get go multiple Executives are partially resurrected, its revealed Yellow Keeper created the Invaders, its also revealed the Divine Tools are all derived from clones of Yumeko, the dopey couple that keeps getting into trouble are actually Executives, the Dragon Keepers are seemingly defeated in one chapter then demolish the Executives in the next, and it all culminates with the return of the Giga-Invader Death Messiah. Add this to the fact that Four Lines, All Waiting is in full force here because this arc brings back most of the manga's very large cast, and complaints that it has become hard to keep track of the events of the arc became common.
• Ass Pull: Akane Yamabuki's backstory and Face–Heel Turn in a nutshell. Her focus chapter initially started off with portraying her as a by the books youth and Ranger, but after a brief "Reason You Suck" Speech by Yellow Keeper it turns out that Akane was an Unreliable Narrator as she was really deluded into thinking she was a good person. To say it came out of nowhere and went from 0 to 100 really fast is an understatement.
• Fan Nickname: Ranmaru Koguma is sometimes called "Ranger Mineta" due to having a character design that has some striking similarities to Mineta from My Hero Academia. Particularly the two of them being short midgets, and Koguma's afro-like hair looking similar to how Mineta's head has sticky superpower balls acting as his hair.
• Harsher in Hindsight: When Sanae and Momoji are first introduced, they come off as friends or family of Chidori living in seclusion because he keeps as much of his personal life a secret to everyone. When they're reintroduced during the Red Ranger's Amnesia mini arc, they have moved to the slums outside of Milky Way City as its revealed towards the end of the mini arc that Sanae has been targeted by the Rangers Association for a very long time. It's heavily implied Chidori's presence kept the Rangers Association away from them so with him recovering from wounds sustained in the previous arc, they were forced to flee without his protection.
• It Was His Sled: D successfully infiltrates the Ranger Association disguised as Hibiki Sakurama. Since it happens early on, and so much of the story revolves around this switcheroo, it's almost impossible to discuss the plot and its characters without giving this away. It also doesn't help that one of the volume covers shows off D-Hibiki, and the intro and ending for the anime adaptation doesn't even bother hiding how important it is that D has to disguise as Hibiki.
• Memetic Mutation:
  • Due to the nature of the series being about an invader footsoldier who's tired of constantly getting beaten up by a group of ranger heroes that have a major case of Villain with Good Publicity, comparing the series to The Boys (2019) is quite common. "Red Keeper = Homelander" in particular is seen a lot.
  • "This too was foreshadowed." ^Explanation A quote from Yakushi Usukubo regarding the fact that he's an Otaku who loves the Invaders due to a past show that was on VHS. He tends to believe that certain events going on in the present were "foreshadowed" by the show. This has since become a viral joke amongst readers that whatever Yakushi does next, especially if something doesn't go his way, that too was also foreshadowed.
• Misaimed Hatedom: In Japan, reception towards the series is much more lukewarm as Super Sentai fans in particular see the series as a edgy Shallow Parody of the type of shows it's based on.
• They Changed It, Now It Sucks!: A minor nitpick some have regarding the official English title is that Ranger Reject had more uniqueness to it over the Power Rangers inspired Go, Go, Loser Ranger! title. To be fair, the Ranger Reject title is fan-made, but that doesn't stop some people from complaining.
• They Wasted a Perfectly Good Character:
  • The Dusters. While their sorry situation was what kicked off D's character development and we get to see standout Dusters such as F and XX while the Invader Rights Association uses them as their justification for opposing the Rangers, the Dusters themselves get very little spotlight and no insight into their situation from their own perspective. We get it teased when Footsoldier A is downright confused when Hwalipon cooks up a fake Sunday Battle during their own fake battles, but we get nothing else.
  • The failed ranger cadets, Ranmaru, Yamato, Renren, and Tsukasa, end up dropping out of the story after the Bailong Exams, which can be a bit disappointing after how much time was spent on building them up as characters. At the very least, they start appearing again about 60 chapters later during the Three-Way War arc.
• They Wasted a Perfectly Good Plot: Some fans argued that the Three-Way Battle arc robbed the story of slowly exploring the other Ranger battalions after getting thorough looks into those for Red, Blue, and Green. We at least get to know the functions of the Pink and Yellow Battalions, and some members are highlighted in the Three-Way Battle arc; but both are packed into an already condensed arc with multiple focus characters, leaving little breathing room for them.
