I'd say a 3.something/5 movie, like 3.8/5. It was pretty good, enjoyed it a lot. I think they really pushed it by veering off into a different genre, family values drama/moral parable approaching the halfway mark, slowing the film right down, staying there too long and returning to the supernatural monster confrontation right at the end, almost so briefly it was like an afterthought they just tacked on. I thought it seemed almost a bit self indulgent and insular of the filmmakers, hijacking Ghostbusters for their own purposes, using it as a framework for their family drama. Which I don't mind, I liked the story and their use of that genre. They're nice characters, great actors and for the most part it was nicely done, lovingly made, carefully paced and sensitively scripted. But yes, I think that section dragged on a bit too long at the expense of the return to the supernatural fantasy themes at the end, it felt imbalanced. However, I came out of the cinema feeling strangely satisfied, it was a pretty good film overall with a lot of good material and I enjoyed it quite a lot.
