Movie bearable because Drax was hilarious (SPOILERS)

Rating: 4/10 (8 May 2017)

SPOILERS BELOW
I had quite high expectations as I really liked the first movie despite not being a huge fan of superhero movies, even those widely regarded as great. Well, when it came to visuals my expectations were more or less met even if the Stormtrooper level of shooting was awkwardly bad at times. It wasn't marvelous but no complaints. The main characters worked out fine together, just like last time. The rest sucked.
The only characters that had a real reason to be in this movie was the guardians, the villain and to some extend extra daddy Yondu.
The golden people in the start? Attacked with spaceships twice and that was it, didn't matter to the plot at all.
The sister of Gomora? Completely pointless, first tried to kill her sister then they suddenly become friends again, after that she is unnecessary.
Yondus gang and people that stopped working with him etc? Worked as motivation for him to join the guardians and help out but played a far too large part for just introducing Yondu.
Yondu? Nice seeing him again after the last movie as he is an interesting character. He matters in this movie as it is pretty much about the main characters backstory, where Yondu was more or less the father. There is also a quite nice scene with him in the end.
The plot? You don't know what the movie is about until Ego aka biological daddy suddenly turns out to be a bad guy with a weird motivation. I think that happens 20-30 min before the movie is over, which makes the story from there on far too stressed and fast. The only things that mattered in the movie before that is that Ego picked up the main char and that Yondu got thrown out of his gang by mutiny. This could have been done in 30 min, then 60 min could have been spent on getting to know Ego and gradually showing how he was a bad guy instead of it coming out of thin air. Make it like that, meaning 90 minutes long, and it could have been a decent movie.
The only reason I don't give this movie 1 or 2 is because the "jokes" where Drax and the antenna girl don't have any social barriers and speak the truth all the time were hilarious and made parts of the audience laugh out loud, including me.
