The first half of the film is a real adventure about Hugo, Isabelle, and the message in the automaton. But the film soon turns into Scorsese's movie about his love of movies and that, for me is when it got really interesting. I won't say what happens but it involves a movie director and him trying to forget his past career.
The 3D is very good, with some scenes that seemed to pop off the screen. The 3D didn't blow my mind but the scenes with snow were amazing.
The film has some bad spots though. Firstly it is too long, and there was certainly a lot of stuff that was not in the book that could have been cut. The whole subplot about the Station Inspector could have been cut out of the film along with the subplot about the bookkeeper (Christopher Lee). It also moves very slow in some parts, and small children may get very bored, but for any true cinema fan, it is a true treat to see the movie, especially the parts about Melies.
The acting is very good all around. Butterfield and Moretz are great actors, but the best performances come from Kingsley and Helen McCrory who plays Melies' wife. There are no bad performances. Even Sacha Baron Cohen's the Station Inspector is very good, it's just useless to the plot.
In the end, Hugo is a delightful family film that all movie fans will adore. I can't recommend it for kids, not because of bad stuff, but because they will be bored. But everybody else should definitely see it.
THE FINAL GRADE: B+ (8/10)
