To quote Roger Murtaugh - I'm too old for this shit!
Don't get me wrong, there's plenty to like if you're still an MCU fanboy. This is not anywhere close to the first movie but somehow more tedious to watch than the second movie (which I don't really like). After all the sugary high from raunchy jokes and cameo fest, there's absolutely nothing to it. Yeah this is not that important movie to save MCU.
