Here's how not to do a sequel

Rating: 4/10 (7 August 2017)

OMG, what a terrible sequel to one of the best movies of the decade...
Shallow, unfunny, clichéd, predictable and often pathetic, in many places poorly acted and directed, with overabundance of cheesy fake-looking rainbow effects.
It's like writers read all viewer comments to Vol.1 then added whatever people liked 100 times over into Vol.2. So the lovely 80s music vignette now becomes massive bore shoveled into every scene, complex Yondu-Peter relationship gets butchered into cheesy pathos, Yondu's character gets reduced to repeating Vol.1 whistling scene over and over, Rocket goes boring with highlights being Vol.1 repeats, Gamora/Nebula relation - again repeats, Groot no development at all beyond Vol.1 ending cute cgi.
The only character that actually gets improved is Drax, his lines are written and get delivered in the best manner of the first movie, unfortunately that can't keep this wreck afloat.
