History YMMV / GuardiansOfTheGalaxyVol2

* TheyWastedAPerfectlyGoodPlot: Mantis and Peter have little to no interaction aside from a brief gag involving Mantis exposing his feelings for Gamora. In a film that focuses heavily on family relationships, many consider it a wasted opportunity as Ego raising Mantis makes her and Peter adoptive siblings (and a deleted scene confirms that Mantis is actually one of Ego's children making them half-siblings), though no meaningful moments come of this.

* EvilIsSexy:
** Though how evil she is is up for debate, Ayesha is definitely an antagonist, and played by gorgeous StatuesqueStunner Creator/ElizabethDebicki. [[GreenSkinnedSpaceBabe The gold skin, eyes, hair, and wardrobe help.]]
** And of course, there's Creator/KurtRussell as Ego. While undeniably monstrous, he's quite the SilverFox.

* WTHCastingAgency: Music/MileyCyrus having a cameo at ''all'' got this reaction from a bunch of people, but the reactions were even more confused over the fact that her character is traditionally a [[spoiler:masculine android]] in the comics.

** Extra bonus points go to the earlier scene where Peter [[spoiler: learns Ego [[YouKilledMyFather killed Merideth]] and his first reaction after asking "What?" is to ''[[ThereIsNoKillLikeOverkill shoot him repeatedly with his laser guns,]]'']] which is what any viewer would've done in his position.

** Creator/DaveBautista is only involved in one fight scene in the entire film (specifically, the opening credits). He spends all his other screen time being the comedy relief, displaying surprising and impressive versatility as a thespian. And when the scene requires it, he's fully capable of playing Drax's serious emotional beats with complete sincerity. Special praise should be given to both him and Creator/PomKlementieff in the scene where Drax allows Mantis to feel his grief over his dead family -- Klementieff's broken sobbing contrasted with Bautista's [[StepfordSmiler gently stoic smile]] makes the scene ''amazingly'' effective and heartwrenching.

* BaseBreakingCharacter:
** Well, less "character" and more concept here, but the point still stands with regard to Baby Groot. He's either a refreshing way of handling the character after the first movie or a cynical move by Marvel [[MerchandiseDriven to sell merchandise of the character]]. [[spoiler:Teen Groot gets this same treatment.]]
** Either you like the inclusion of Mantis as a funny, endearing, PragmaticAdaptation for a new TokenGoodTeammate who bucks stereotypes by avoiding the AsianAndNerdy trope and being [[HeartIsAnAwesomePower a surprisingly effective]] NonActionGuy, or she's yet another demure female Asian-coded stereotype that doesn't get a shred of her comic counterpart's badassery.
** Drax being DenserAndWackier as opposed to being TheComicallySerious either made him more iconic or more obnoxious.

* {{Narm}}: While the first movie had a decent balance between humour and drama, this one definitely leans heavily on the former and not for the better:
** The stretching of jokes getting drawn past the point of humour, to the point where it feels like it was better left on the Blooper reel. Whether it's discussing Yondu's finn.
** Drax asking Ego if he made a penis isn't bad. Ego actually answering the question kinda is, since, how else did he conceive his son?
** Mother. Fricking. Taserface. The character's name alone is cringeworthy, and as Rocket jokes, he looks more like a specific body part. Then there's the fact that the moron doesn't actually tries to explain the reasoning behind his name. The idea that he knows of a word like: "Metaphorical" and yet has no idea how to use it, is weird.

* CompleteMonster: [[spoiler:[[Characters/MCUEgo Ego]], [[Characters/MCUPeterQuill Peter "Star-Lord" Quill]]'s [[ArchnemesisDad father]], is an immortal Celestial, who once traveled the universe seeking companionship, but found that other life utterly disappointed him and lost any interest in them. Ego instead decided upon a plan of [[AssimilationPlot assimilating all creation into himself]] in what he termed "The Expansion". Lacking the power to do so on his own, he sired countless children--[[Film/TheGuardiansOfTheGalaxyHolidaySpecial including Mantis]], whom [[AbusiveParents he treated as no better than a pet]]--hoping they would inherit his Celestial powers, [[OffingTheOffspring killing them]] out of disappointment when they didn't. Traveling to Earth, Ego met Meredith Quill, whom he developed genuine feelings for. Unwilling to deviate from The Expansion, Ego [[KickTheMoralityPet gave her the brain tumor that killed her]] to ensure nothing held him back from his self-appointed purpose. After learning Peter might carry the Celestial gene, Ego tracked him down, playing the good father to him before revealing the true purpose of The Expansion, revealing his true nature when he believed Peter wouldn't care. When Peter turns on Ego, Ego enslaves him to his own power to use Peter [[LivingBattery as a battery]] for the next thousand years before kicking off The Expansion to consume every living thing in the universe, while spitefully [[CrushTheKeepsake destroying Peter's Walkman]] which was a gift from Meredith and his last link to his mother. When Peter attempts to stop Ego, Ego without care also tries to murder Peter's friends.]]

** It's safe to say no-one expected The Watchers to show up. Much less in Creator/StanLee's obligatory cameo, where Stan seemingly talks to them about his previous cameos, all of which amounts to a certain form of Ascended Fanon.

** Drax being DenserAndWackier as opposed to being the ComicallySerious either made him more iconic or more obnoxious.

* SpecialEffectsFailure: In the scene where Peter and Ego play catch with the orb, the background behind them is obviously green screened in.
