It is my sad duty to inform you, my readers, that Timeline is a steaming pile of poo. Let me ruin it for you:
The surfer and the cute chick live. The professor lives. The French guy dies. The British are being assisted by an evil scientist from the present day. The professor and the Hot Scottish Guy (who also lives, but stays in the past) blow up the English fortress with gunpowder made by the professor as part of a bargain to keep from being run through by the English lord. The sarcophagus with the portrait of a one-eared lord? It has the Hot Scottish Guy and the Cute French Girl in it.
The cliches run rampant like… like… cliches at a college Renaissance festival.
The best actors were the trebuchets.
You have been warned.
