I wouldn't have liked to see anyone else in the film - establishing them all and getting them all together took enough time anyway, IMO - putting in other characters into an origin film would have just meant more time needed to be put into exposition, establishing them, and getting the team together. As it is, we've got a really good starting point. I'd love to see (and expect to see) other characters brought into future GotG movies though.

(And I think we've got what we need to introduce Nova and Adam Warlock now).
