My favorite parts of THE PLAN were Anders' moments. There was also a well performed added cylon retcon but it was mixed into this other ridiculous storyline of the "plan" so it wasn't satisfying overall.
I just think THE PLAN, from both concept to execution, is a demonstration of why I feel BSG and LOST ended the right way. When you explain too much, or sometimes anything, you are more likely to disappoint the audience. And I think I was more disappointed by them explaining things than I have ever been in NOT having something explained.
Granted, the way CAPRICA ended may be the new perfect way to end a series. Show what happened down the line and then leave it up to the audience to decide what may have happened after that.
