The Justin Timberlake movie "In Time" looks awesome, but I bet it's not.

I absolutely LOVE the premise of this movie.  Time as currency?  Buying a cup of coffee cost 4 minutes of your life?  There are endless possibilities and cool things that could be done with this concept.  And that is exactly what's going to ruin it.  48 seconds into the trailer this flick already has way too much on it's plate.  Instead of being a movie, I wish "In Time" was a new series debuting on HBO or AMC.  Then it could delve into all kinds of potential plot lines and character development without having to wrap everything up in 2 hours or less.  As it is, I'm guessing the filmmakers ran out of time themselves, and the movie falls way short of it's potential.
