It's not really important for the VII to be Anakin's history: It's better to tell someone else's history than, for example, resurrecting Vader (that's something I FEARED could happen). 

Furthermore: I always thought it is the story of R2-D2. It's the only one who actualy knows pretty much everything! :-D

Anyway, I essentially feel disappointed by the lack of importance of the old Characters, and how they are forced to give in the leading role to Rey "Know-how-to-Jedi-out-of-nowhere" BB-8 "Despair-thoseofyou-who- were-fans-of-R2" and Kylo Ren "The kid" :-( Seems to me as puny, badly constructed characters, not up for the heritage. But not up, in the meaning of... the script not even trying.

The Starkiller Base is also a kiddish attempt to "be bigger" than the Death Star. And absurd too: the two first Deathstars bleed dry the Galactic empire's coffers... but the First order, an essentially much smaller organization has created Something much bigger, able to fire at hyperspace speed. Yes. Of course.

Sorry. This has probably been a rant. :-(
