Had me captivated to the screen for the full ~2 hours!  I missed the first hour taking care of my little boy.
I was in the second grade when BSG came out...  I loved Boxey and Muffit.  
This new one had some great high points...  combat scenes were more scientifically accurate but hard to track/watch at their small size and high velocity.
And they SO wimped out on blowing up all the sub-light vessels that couldn't jump before the surprise attack - fade to white?  BOOOOoooooo!!!
Cylons = computer programs which can be implanted into a human brain?  Cylons running around in robot bodies is true to the original, but human clones??  What was THAT all about?   
Baltar having sex with a Cylon blondie for two years??  
I could have sword the original Cylons (if you read the books) were insectoid, not "software".  The "robots" were simply powered armour suits.
I liked the light peppering of old phrases like, "Life here, began out there..."  
Starbuck = FEMALE??!?!!?!?!?!?!?!?!??  
Overall, good....  but not awesome.
"Fleeing from the Cylon tyranny - the last battlestar, Galactica, leads a rag-tag fugitive fleet on a lonely quest...  a shining planet, known as Earth!"
