I liked it. Sara and time travel were what drew me in the first place, but I enjoyed most of the characters except for Hawkman, Hawkgirl, Captain Cold, and...well, Vandal didn't do much in this episode, but I didn't care for him on Arrow. Snart would be a good character in theory, but he's too smarmy. I don't watch The Flash, but here he's like a moustache-twirling "mwa ha ha" sort of villain instead of a real person. He needs to take it down a notch.
