Guardians Vol. 2

Regarding the Adam Warlock thing, he isn't in the movie per se, but the high Priestess of the Sovereign people creates him during a post-credit easter egg. He is apparently her twin, and in the comics Adam posessed the Soul infinity gem, so this is likely the reason for his inclusion. As to whether he will be a dick like he was in the books or more of an anti-hero like she was when she was known as Paragon, only time will tell. I have a feeling the Golden arcade fanatics will be important to Thanos in some form or another...

My only issues are with Peter's father being Ego, his involvement in Meredith's death and lol villainous monologue seeming like it was forced, over explanation or emphasis on some gags, and humour being thrown in at weird times like in a scene directly after Yondu's loyalists were spaced.

On the flipside, Drax adopting Mantis as a surrogate daughter, Ego's and Peter's game of catch, Nebula viewing Gamora as a sister the entire time, Peter not bursting Yondu's bubble about who Mary Poppins is, letting him bask in the praise, Yondu's pride in being considered a badass by his son, Yondu's reaffirmation about being Peter's pops, subsequent sacrifice and funeral hit me in the feels.

Also whatever make-up+Ggi technique Gunn used to make Kurt RusselI look younger i wish it was used for Leia's cameo in Rogue One.
