If your favourite part of the main game was stopping to read documents every 5 minutes then I have amazing news for you.
For real your enjoyment of this DLC will depend entirely on how much you care about learning about the Croft family history.
Edit: This used to be a sole page for Blood Ties DLC, but it's now updated to include a full celebration pack which had "Lara's Nightmare" too. Unfortunately it's been too long for me to properly review the mode, but I did remember it being pretty fun if not repetitive towards the end.
