Things Past

The audience is allowed to stay far ahead of the four main protagonists of this story. We know that whatever they are experiencing, it's happening in real time and only in their own heads.

So it is again very painful to see them promote the false theory that they have somehow traveled back in time, especially when they worry and fuss about all their fears of choosing their way into some new line of history. Bugger. This section is just a waste of time and a red herring anyway, and the episode would probably be better off if it dropped such bits.

All in all, the episode is okay, but a bit on the dark and depressing side. It is kind of cool when we find out what has caused all this to occur in the first place, but for what we specifically learn about the past of one of the characters, it hasn't really added something worthy to the canon. It is a worthy period to explore, but somehow felt as if we got something a bit too far out of character, as though death and loss were once more forced onto the episode as someone's writing crutch.
