I loved it. It is at least tied, if not surpassing Empire. Now for my thougts:
(1) Saw Solo dying a mile away. Ford was done with role and they needed to kill him off, but they needed to do so in a meaningful way given his status.
(2) Rey is definitely Luke's kid. So, one has to wonder if they're going to introduce a Mara Jade like character (maybe Kylo killed her). Kylo's story seems to be a re-worked Jace Solo storyline. Or, Luke's Lightsaber is now a force relic and if so, it will amplify the force abilities of the wielder (but then again, that's EU so may not be true).
(3) IMO, the odds on favorite is that Snoke is Darth Plagueis and here's why:
(a) The rule of two- sure there are always going to be secret apprentices but not secret masters.
(b) Darth P "unlocked the secret of immortality". He was probably too weak to strike Darth Sideous down, so he let him proceed with his plan/ Sith think in the long term i.e. the whole Clone War was just an excuse to have a clone army that could carry out Order 66.
(c) Darth P doesn't have to be Munn. Remember, all the EU is non-cannon. Its just like JJ Abrams to throw a twist in a familiar plot i.e. the white guy being Khan.
(4) Luke may want to draw Darth P out and going into hiding will do that.
(5) Regarding Fin and the lightsaber, I think the New Order Troopers are trained to fight against lightsabers i.e. the trooper with the baton.
(6) I didn't have as big a reaction to the destruction on Hosnian Prime, but I think that's true for two reasons: (1) we didn't the actors reaction..remember the sheer horror/terror on Leia's face? that will invoke an emotional response from the viewer (2) We're older now.
