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.
YMMV: Gatchaman Crowds
Base Breaker: From the first episode itself, Hajime Ichinose was either adored for her loud attitude and considered the high point of the show, or she was alternatively considered to be obnoxious and criticized as one of the weaker parts.
On the other hand, episode 2 has shown more of her caring and friendly aspects (even going so far as to befriend a MESS), which has won over some of her detractors. The more cynical among her haters, however, point towards this as evidence of her being a Canon Sue.
Crowning Music of Awesome: The entire OST qualifies, but Gotchaman~In The Name Of Love, Music Goes On and Unbeatable Network really stand out.
Ear Worm: The background music during Gatchaman's transformation sequences.
The opening theme, "Crowds", is also rather catchy.

More Popular Spin Off: The show was undoubtedly an attempt to cash-in on the live-action film adaptation of the original Science Ninja Team Gatchaman, which premiered around the middle of this show's run in August 2013. The movie got poor reviews and was considered a flop, while this show has signs of becoming a Cult Classic...and got a second season!
Mary Sue Traits: #1: She single-handedly proved that the Gatchmen's long standing intergalactic policy of remaining hidden from the public was a counterproductive security measure on earth. #2: OD spent half an episode gushing over how wonderful Hajime was, mentioning that the greatest thing JJ ever did was let Hajime be a Gatchman, and then stating it was an honor to live long enough to encounter someone like her.
Failures: #1: She has trouble seeing Berg Katze regardless of whether or not he was trying to be invisisble despite her best attempts and as far as the plot goes, it didn't really matter. (Minor Failure) #2: She couldn't talk Berg Katze out of his plan to destroy the world despite trying her hardest. (Major Failure) #3: Inability to quickly, consistently, and properly convey her thoughts to her fellow teammates, thus wasting time, energy, and damaging the team's dynamics. (Major Failure)
Results: Possible Justified Purity Sue (first example). Even though the Gatchamen thought Berg-Katze was unstoppable Hajime managed to beat them by making the world a better place so it would be immune to their influence and while the events leading up to it are unknown: she becomes the "caretaker" of a sealed Berg Katze. All her decisions, no matter how outlandish or inappropriate they seemed, have positive outcomes that no one else ever thought of except her and OD's gushing over Hajime's positive influence on the team would make her a minor Canon Sue, except for the fact that she has plot-relevent character flaws and still lacks in the "Beloved by all" requirement and none of those that hate or annoyed by her are never shown as being wrong for disliking her which are all instant Mary Sue disqualifications.
They Changed It, Now It Sucks: The most vocal reaction before it even aired. Classic Gatchaman fans were not very happy once it was revealed that the anime would have a completely new cast of characters and an entirely different setting compared to the original. Most criticism and controversy appears to come from the birdstyles being gone, the entire origin over the team's powers and the "Gatchaman" concept being overhauled, and the existence of a camp gay transvestite on the team. Otherwise, the In Name Only nature of the show and the team not being the original Science Ninja Team helped sour the reception.
Some classic fans were also annoyed by the overhaul done to Katze, in which he was a former Gatchaman and alien. Although, the new Katze also has his fair share of fans.
Viewer Gender Confusion: Rui Ninomiya is described as a boy in NTV's English press release, and has a male voice actor, but other translations of articles referred to the character as a woman. Needless to say, the character's androgynous appearance and these other factors lead to quite some confusion with fans. This was played with in episode 2, where it was revealed that he crossdresses as a woman.
Notably, Berg Katze has so far only been referred to with neutral pronouns.
The Woobie: Rui, starting around the time he/she gets beaten up by Katze, loses control of the GALAX system to Katze transformed into an Evil Twin of Rui, and starts having frequent Heroic BSODs.
