Missing sub-plot?

Rating: 3/10 (4 March 2012)

I went to see this movie with an open mind. I'm a big fan of several of the actors and Scorsese too. Sadly, I was disappointed.
Don't get me wrong, this is a beautifully shot movie, even in the 2D version, but there are so many things that are never explained or explored, I keep wondering if there is about an hours worth of plot that ended on the cutting room floor.
(SPOILERS) For instance, why is a superstar like Christopher Lee cast as the book store owner with about three lines and two scenes? It's obvious that he knows the name Cabret very well. This is not explored further. In his second (and last) scene with Hugo, he gives him a copy of Robin Hood. This seems to be of some importance. Nothing more comes of this, making the whole second scene pointless.
There are several other plot holes (or, at least, depressions), but I'll let you judge for yourself. I found it made for a very weak story. And then there's a bit of overacting, but I expected nothing less.
3/10. Scorsese can do better than this.
