Although it has its amusing moments, in eneral the plot does not convince.

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.
