Just watched Bronson the other day. Tom Hardy was simply magnificent, but the film was kind of boring for me, nothing really happened. Perhaps I started with too much expectations tough after my friend told me it was very much like Clockwork Orange. The music gave a very similiar feeling to the movie I have to admit and that scene when Bronson was released and went home to his mother was also familiar. So I can see the reason for the comparison but they're just not in the same league for me.
However it did got me into watching Hardy's other projetcs, I just rented The Take, Locke and Legend (though it has shit quality so I might wait with that one).
