I thought this was ok....

Not brilliant...but good enough. I like the questions they are asking. The..."can you change the future?", "do you have the right to change the future, even if you know people get hurt?" questions.

I'm glad the BBC are (finally) trying to make something a little bit different, rather than relying on the crime thrillers and costume dramas.

Yes, they can be good and well made too, but there was a time when they were doing very little else.
