Its failure shouldn't be pinned on him. Most critics say the concept was not well executed and I don't think anyone was especially wanting or anticipating a sequel to Gnomeo & Juliet. So far the box office for Sherlock Gnomes is as follows:
It was released in the UK on May 11th, but unlikely to make big numbers there compared to how well Gnomeo & Juliet did. I wish it could make it to $100 million worldwide but that is not going to happen. Maybe it will do okay on release on demand and DVD.
Well, I am not a kid or a parent of young children, but really nothing really clicked for me in the trailers etc. I find the idea of a series of movies about garden gnomes strange. Kind of like an old time children's amusement park gone berserk, you know?
