Alcatraz reminded me the concept of the upcoming movie Looper, except in the movie they are from the future.
I fairly enjoyed it but I feel it will be a hitman of the week storyline. Slow and layered revealing of the secret will take place until the season finale.
Having said that... the acting in "Alcatraz" was just horrible. The female lead was terrible, Hurly was Hurly, and even Sam Neil was weak. Hopefully they'll improve, but "Person of Interested" is better acted and has better written (from a character standpoint).
know JJ Abrams won't be able to resist having a good chase scene. So, cute, tough blonde girl with attractive short hairstyle and a muscle car = I'm watching for the full season.
