Gotta say the music just doesn't do it for me this time, I'm not really a fan of that era of music so it all just washed over me. I like Surrender and The Chain though because I'm a human being, but other than that I largely felt those scenes fell a bit flat. They relied too much on Drax for humour even though he was great, and overall the story just didn't quite hit it off for me.

Ego was a total waste in my eyes, in both concept and execution. Allow me to don my "here's how I would have done it" cap:

Ego is a big living planet! That is cool, I like it! However, him settling on the Kurt Russell form is basically designed for a joke that I think ultimately circumvents the ability to be interesting with him as a design. It would make more sense, in this largely bipedal occupied universe, for him to be something more ubiquitous, say a glowing white Mr Manhattan type. In the diorama's he showed us he could have been said ambiguous white figure. 

When he encountered life he could have transformed to match them and seduce them - that gives us Kurt Russell ego. The kicker would be that he would remain as the Kurt Russell form indefinitely after falling in love and creating Quill, as an act of deception masked as empathy. The reason I feel they should have done this is because... evil Ego is boring. He's a celestial, and making him a rocky Kurt Russell is boring. 

It reduces his big final battle from to... Kurt Russell and tentacles, when they could have gone with something really interesting to match the far our nature of the inside of Egos planet, and we could have had a better final battle than Ego and Quill bashing each with fists made out of styrofoam rock. "Unmasking" him from Kurt would also resonate well with his dehumanising attitude towards the end. Anyway this is just me talking fiction 101 out of my arse, but his lack of development really harmed the film for me and I think this is one of many possible ways they could have improved it.
