There are two types of beings in the universe: those who dance, and those who do not.

Guardians of the Galaxy Vol. 2 (2017)

Chosen by me as I like to go to the cinema a lot and the first one was chunks of fun.

Though it is funny (and that's enough) Gunn seems bored by the fight scenes and,  2/3 times, does a hacky joke where the action is happening in the background and the foreground is a contrasting mundane thing - though at least it's not the really bad just reaction shots malarkey.
The way the first integrated the music went beyond trying to sell a cool tie in album and made for an unexpected emotional throughline - here the daddy issues are more rote and having a discussion over the meaning of one of the songs meaning seems a forced way of replicating it.
There's a really, bizarrely strong fast and the furious vibe going on through the whole movie with it's emphasis on family both by blood and by choice, and baddies becoming staunch allies with little to back up the heel/face change.
The first one has a dull villain but at least the plot's structure makes sense, this one seems to meander for a while then suddenly darts all over the place (i mean i kinda adore Stallone's team but why are they taking up time at the end? that whole ravagers plot is super clunky).

Still despite these flaws making it not quite as good as the first one it is hugely enjoyable, fun, silly, exciting - hard to be too disappointed by that really.
