GOTG was like one of those pop songs on the radio that get the hell played out of them.
As a film, I found the movie to be EXTREMELY immature (drunk dialing Ronan, the dick message, Nebula flat out calling Gamora "stupid", etc etc). It also spent too much time having other characters verbally tell us who someone else was and what they were capable of.
Gunn even stole one of Whedon's beats from The Avengers by having Groot maliciously slam those Sakaarans over and over (ummmm Hulk/Loki scene?). Then there's Chris Pratt fan. I'm a huge fan, but I could barely stand him in it. What was with all the "bro" talk? He was completely off the leash. Thank God for the Thanos scene as that's really all I cared for. Seeing two heavyweights like he and Ronan in a heated argument, t'was a total geek out moment. Just wish it would've last longer.
Pratt's performance in GOTG was almost a complete opposite from Paul Rudd - who's comedic style I felt was muted a bit in Ant-Man.
