I went and saw this movie a couple weeks ago. I have mixed opinions on this one.
Okay so starting with the good stuff in Guardians 2. The gold people are the best thing in this movie. The idea that this pompous race has somehow become so advanced yet they can't even roll the carpet out for the high priestess is genius. Then they had those space drones controlled by arcade machines to save themselves, ha! That one made me laugh out loud. We need a whole movie about these guys.
Then there was baby groot. I know a lot of people liked him, but I just couldn't get into it. That opening scene where he's dancing in front of the camera annoyed me. It triggered my Alvin and the Chipmunks ptsd where a cute character dances like an idiot in front of the camera as an obvious ploy to appeal to children and sell merch. Hated it. Then star lord and kurt russell met and played catch with a little blue ball of energy and I facepalmed at how childish that whole sequence was. Then Kurt Russell revealed the whole brain tumor thing for some reason. Then at the end, the movie went full on star wars rip-off when they had to destroy the planet. It's a cliché at this point and needs to stop.
pros: The gold aliens, some good character development, good effects
cons: Too many jokes, some very juvenile. Snake Plissken revealing his secret plan. Blowing up a planet for the 10 millionth time.
Anyways, people online are praising this thing like it's the second coming or something. I thought it was alright but nothing spectacular. Maybe rent it once and check it out.
