Similar to Boyhood?

Haven't seen this yet, but from the trailer it looks a lot similar to boyhood.
Obviously it came out a year earlier, but also didn't get as much attention as Boyhood is getting now.

Can anyone shed some light? If you've seen both, are they similar?


Boyhood is a drama. American Promise is a documentary, following two real people. They are vastly different.


loved boyhood. looking forward to this


It's more like a "reality TV" variant of the Up series, except publication of each "stage" was deferred and combined into one picture, and it only covers two subject individuals. It's a documentary not a drama as other replier have pointed out. But that's basically the key distinction between American Promise and Boyhood. The term "longitudinal study" is very loosely related to the manner of documentary.
