Kind of pedestrian, but barring the back to the future rip off one they've all been a bit paint by numbers, but particularly the last two (I think its the same director for both, and unfortunately I think he's making the next two). This one was a lot more 'uneventful' than the others, so will probably be panned (I've not read any reviews).
It was okay though, but it wasn't really as 'magical' as this type of film should be

edit: "prisoner of azkaban" - if anyone is wondering which one I was gibbering about.
