I liked it. It was a bit limp in places, yet there was usually something each episode that made me think it was better than it was, and I never really toyed with stopping watching it (though if it'd been 20+ episodes rather than 10 I might have). On the whole I thought it meandered a bit too much, but crikey the last 2 episodes were really good, and I'm intrigued as to Alec's comment about why she won't believe why he sent her back. I'd put it on a par with Terra Nova as a show I'm quite happy to keep watching, but I'm not gonna cry if/when it gets cancelled.
^ Well second season was greenlit before the show even started airing here, so it's not getting the Terra Nova treatment yet. I'm hoping the series will look at what worked and what didn't and give us a stronger season next time around.
