Bad science

From BBC News:

Is it much of a surprise that The Core is said to be the most scientifically inaccurate film, any moron watching that film knows that the entire plot is complete rubbish!

But on the other hand isn’t a science fiction film supposed to bend the laws of science occasionally, otherwise it would just be a science film! Ok I am not allowing for those films that are science fiction because they have discovered something in the future that may kinda be possible at some point.
