It's not terrible, but if give it a miss. Just a really flat script. I know this is a children's film but there just aren't enough laughs to keep adults interested. It's got 'trilogy syndrome' like the godfather: first one is great, second one brilliant and third one really disappointing. The director of the first two, Paul King, passed on it as did Sally Hawkins. If they do a fourth one expect more of the cast to be replaced.
