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: Guardians of the Galaxy
Base Breaker: Angela, who is either a badass Action Girl who complements Gamora, or a bland character and a pointless addition to the team.
A rift seems to have developed between fans of the most recent team led by Star-Lord and fans of the original team. Especially when the 2014 film was merely being talked about, and was set to include Star-Lord's team; which eventually turned out to be the case.
Some Spawn fans are not happy about the appearance of Angela in the current series.
Volume 2 not featuring the same team who were in the original series.
Before volume 3 had been released, some fans were not 'pleased' with Star-Lord's retro inspired redesign nor Gamora's costume changes, and let's not even start about the inclusion of Iron Man to the cast.
Rocket Raccoon in volume 3 is not as well liked as he was in volume 2, mainly because of how he gleefully shouts about murdering enemies, and because he now seems to have a disdain for Earth, both traits that had not been there before. On top of that, his origins being changed from a mutated raccoon to a member of a race of aliens that look like raccoons.
As of issues 7 and 8, both complaints about Rocket Raccoon seem to have been addressed, as Rocket referenced his original origin and other character have discouraged Rocket from using his new catchphrase as they find it "annoying and disturbing."
Bring back DnA(Dan Abnett and Andy Lanning) has pretty much become the fandom's catchphrase.
The 2013 series being more Earth-focused than either previous series, with the inclusions of Iron Man, Captain Marvel and Agent Venom being commonly pointed to.
April 2014 solicitations revealing that Star-Lord will be undergoing another makeover, this time to his costume from the film set to be released later in the summer.
There's also the involvement of James Gunn at all, after some internet bloggers uncovered his year old "50 Superheroes people want to sleep with" list, which was filled with controversial comments. Gunn has since apologized for the comments, claiming that he no longer thinks that way, but people are genuinely split on it either making him a horrible person who shouldn't be directing, or thinking its just some jokes that got taken out of proportion.
Fans of the original lineup wanted the movie to focus on them or at least feature more of them (only one member is from the original series).
The casting of Djimon Hounsou as minor villain Korath, as some fans had hoped he'd get to play Black Panther in his upcoming film. (Including Hounsou himself, who still wants to.)
As noted below, Brett White was quick to make a post about the audacity of this film and its characters, whilst Wonder Woman's movie debut had been continuously postponed. Not long after, Wonder Woman was announced to be making an appearance in the sequel to Man of Steel.
