The new troupe of heroes from ‘vol. 1‘ have become a team. The talking tree Groot has been replaced by a baby tree, but for the rest, the group remained the same. Even the villains partly did.
The movie is more to the comedy side of the Marvel franchise with silly jokes and screwball humour. The adventure this time involves the father of Peter Quill who may not have such great plans for the universe.
So there is some humour, some drama, some action, a not-too-interesting story. A bit of a filler in the Marvel franchise perhaps. Not even an addition to the Marvel Cinematic Universe it seems.
Not boring, but nothing that needs to be high up on your watch list.
