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
Broken Base: A rift seems to have developed between fans of the most recent team lead by Starlord and fans of the original team. Especially when talk of a potential movie started up and it was based on the Starlord team.
Some Spawn fans are not happy about the appearance of Angela in the current series.
Funny Moments - When Major Victory scans the three Guardians viewing him.
Major Victory: A Spartoi/Human crossblood, a gene-bred post human and a....whoa! Is that a raccoon? That can't be right.
In the first issue, Rocket Raccon tries to come up of a team name, even in the heat of battle.
Rocket Raccoon: Ass-Kickers of the Fantastic?
Rocket Raccoon: How about "Rocket Raccoon and His Human Hangers-On?"
Drax: How about "Drax and His Coonskin Hat?" That grab you?
The revelation that "I AM GROOT!" actually translates into complex Techno Babble.
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. While some fans enjoy this, seeing him as badass because of it, for others it falls on this trope.
Bring back Dn A(Dan Abnett and Andy Lanning) has pretty much become the fandom's catchphrase.
Rocket Raccoon's 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."
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 focus on them or at least feature more of them (only one member is from the original series).
