Guardians of the Galaxy, Volume 2
Pretty much everything you want in a Marvel Guardians movie. The opening titles set the fun tone for the whole movie, though there is some emotional gravitas to it. ELO never sounded better! I rewatched the first Garudians movie before and felt it was like a Star Trek movie. Star-Lord has Kirk's haircut, attitude toward women, but is learning his ethics. Volume 2 is more like a Star Wars movie (I won't spoil the story with evidence of this, but the set pieces and plot devices will be recognized upon viewing.)
The comic timing is sharper, the colors more vibrant, and the music just about perfect, both songs and score. This has quite a cast (Michelle Yeoh has a blink-and-you-miss-it appearance as a Ravager.) Each character is given more background, especially Yondu and Nebula. Rocket and Drax are scene stealers. In both movies, I'm amazed that Rocket has the most emotional resonance, given that he's a CGI critter. They still have a villain problem, but this story is more about character development than galaxy saving. Not sure if they intended this, but there's an interesting political metaphor employing "goldness" as an ideal perfection with a race known as the Sovereign.
Marvel seems to have bifurcated the MCU into the cosmic (Doctor Strange, Guardians, Thor), and the grounded (Ant Man, Civil War, Spiderman Homecoming) It will be interesting to see the direction next year's Infinity War goes. While I found Guardians 2 better than its first one, I'd probably rank it lower, ironically, on the overall MCU rankings. It was everything I wanted and expected, but didn't have the jaw dropping paradigm shift of Winter Soldier or event status of The Avengers. Still, it's a worthy sequel, better than the original, and admirably ties up loose ends from the first. Not sure where they'll go for a third entry as this was a very satisfying sequel.
The last of the five (!) post credit scenes brilliantly ties in all the Stan Lee cameos (comic book fans will know, others should look it up.) The genius of this is Marvel found a way to link Deadpool and X-Men movies into their universe without violating studio licensing agreements. Basically, any movie with a Stan Lee cameo is now in the same universe!
