The movie is set before Infinity War, it's a pretty self contained film, lots of fun. If you are worried about Infinity War spoilers make sure you leave as soon as the credits role.
Do you think you'll be disappointed just because the story doesn't advance the overall plot further? If you enjoyed the characters of the first film I think it is still worth seeing at the cinemas, just remind yourself that it isn't related to Infinity War. Will you be skipping Captain Marvel as well?
