For non-US viewers...
Is this horribly dull and disappointing?
I can usually get into series about anything, even Japanese military stuff, that I have little to no interest in, simply for character or plot reasons, but it seems to me that to enjoy this, you need to come in with an actual intense curiosity into the whole jfk thing.
I'm a Franco fan, a King fan, a period drama fan, it looks nice, the acting is good, but this series is like a blank slate. Any non-US person agrees? Or US, but not a natural jfk enthusiast?
Clever people will recognize and tolerate nothing but cleverness.
