After the fairly exciting return last week, The Event was back to its old tricks, underwhelming and spending an hour doing nothing. The end of "Turnabout" is decent, with Thomas getting hold of nuclear material and Martinez deciding to get tough, but the rest of the episode is dragged down by the usual suspects--Sean, Leila, and a randomly inserted Vicky.
If Thomas caused Chernobyl, does that mean the Russians know about the aliens? Yeah, I don't think the writers thought about that.
Score: 7.5/10
