Oh and 4.0 out of 10 on my scale means that it is just below average.
To give you some idea of what that means I consider Search for Spoke to be a 5.0, so a 4.0 isn't good but it is far from the worst I have seen. if this movie had just had someone with a brain look at it's script and it had been edited down to eighty minutes or so it would have been much better.
Oh and if you insist on putting pointless robots in your movie make them look like something other then cardboard boxes. The robot in a $200 million movie from 2014 should not look worse then ones seen in a 1970s episode of Doctor Who that had a budget of a few thousand dollars.
