I voted B. Lots of style and flavor, but in the end, it turns into yet another bang-blam-bloom battle, revolving around yet another magic doohickey. So this whole cinematic saga is turning into one big Power Rangers punch-up, is it? Er, yay?
Also: of the ten MCU movies to date, ten have starred straight male white leads (all of whom except Thor are Americans, though even he speaks with a much more Yank-ish accent than his father and brother) . True, the franchise has a solid number of great other-than-white supporting characters in Rhodes, Fury, and that Falcon guy, plus May and Skye, and in this movie, Gamora, Drax, Rocket and Groot are all other-than-white to varying degrees, depending on how you count the ethnicty of voice actors, and The Collector isn't Anglo. Still, as good as Pratt was, it could have been nice to see a Hispanic or Asian or something lead. Or, y'know, a woman? A short-haired woman to pair up with the long-haired Gamora, maybe?
I'm not the biggest PC stickler for mandatory diversity casting, but I've been watching Glee this year, which, apart from its standard-TV levels of ethnic diversity, has several gay/bi characters of both genders in various stages of out-ness, plus a trans person, plus several characters with physical and/or mental disabilities. True, it doesn't have any aliens or sentient plants (yet), but it is pretty impressively diverse. So, as weird and wacky as the universe of Guardians is, I was kind of annoyed when John C. Reilly went home to his pink female partner instead of a pink male one. And why couldn't Drax have spoken of a lost gender-ambiguous "spouse" rather than specifying "wife"? AFAIK, apart from Justin Hammer, who has a male squeeze while in prison (har, har) not one MCU character has been indicated as other than straight (Victoria Hand's preferences weren't specified). Kinda deflates the balloon of cosmic weirdness and imaginative storytelling when pretty much everyone, including minor side characters, are hetero, and all the main heroes are white male Anglos, is all.
