There are 80s songs because the movie takes place in the 80s. The plot is well developed. Characters are funny and nostalgic. I think the only thing to complain is that it felt a little rushed. If the movie was an extra 30 minutes longer there could have been more time to bridge the different plot points. Either way it’s a wonderful kids movie and as an adult I thoroughly enjoyed it as well. The CG is amazing and although I was doubtful the voice acting didn’t take long to get used to.
