My wife took me to Guardians of the Galaxy 2 & I was skeptical going in, as I didn’t see the first one due to lack of interest. I was surprised & taken aback by some of the depth of writing, in both character development & the occasional monologue...until every serious moment was undercut with a joke. I mean, Every. Single. One. It robbed the movie of potential gravitas, & frustrated me.
Then when we saw Ragnarok, I realised what a complete cut-&-paste job it was of Guardians 2. People seem to really respond to it, so I guess they’re just playing to their audience, but as you say, every drop of meaning or weight was stripped for a gag. I couldn’t help but see it as a studio paint-by-numbers job.
