You've probably seen it already, but just in case you haven't, check out the pilot for Awake.
After a car accident takes the life of a family member, a police detective lives two alternating parallel lives, one with his wife and one with his son. Is one of his "realities" merely a dream?
Probably the best pilot I've seen this season. Apparently there was some concern that the show might be too difficult to follow -- utter nonsense. The two cases weren't terribly interesting, but there's usually so much stuff going on in a new show (introducing characters, exposition, relationships, etc.) that I'm willing to give it a pass this time. The "dueling" therapists, BD Wong vs. Cherry Jones, worked extremely well. Both present valid reasons why they're not part of some made up world. Looking forward to future sessions.
Some might be quick to compare this to Inception or Life on Mars, but they'd be way off. There's no conspiracy to thwart or daring mission that needs to be completed. The protagonist loves his family and is willing to live in two different realities if that's the only way he can be with them -- even if his sanity eventually pays the price. Works for me and probably lots of folks. Emotional hooks.
Awake kind of reminds me of Passion of Mind, a small indie film from 2000 starring Demi Moore as a woman living parallel lives, unable to distinguish dream from reality. Much more of a Fantasy Romance but still similar. I'd post the trailer, but I couldn't find it on youtube.
NBC's been throwing a lot of stuff against the wall lately. I hope Awake sticks. BTW, you can follow the show's creator, Kyle Killen, on Twitter.
