This show is like watching a Reader's Digest Condensed version of a book but what a ride! There's a cliffhanger, quickly come up with a solution and then move onto the next cliffhanger. To the critics who clearly haven't watched all the episodes, if you're going to watch SciFi genre programmes you have to put your logical mind to rest and just enjoy it for what it is. How can you logically come up with an explanation for time travel? I can't believe how much they managed to cram into just one season and am really looking forward to the next one.
