Saw it tonight, finally. I liked it, and definitely like seeing an unconventional sith here. All of the sith we've seen in the past have been strong, cunning, manipulative, powerful, deceitful. Kylo Ren is more what you'd expect to see from your typical sith recruit: angsty and trying to find the easy way out through the dark side.
I dont LIKE kylo ren, or his personality, but I do like that he's different than what we've seen in the past.
Also, still trying to figure out who Rey is, Luke's daughter or someone else's? Either way, she's hot, and she needs to turn that scavenger staff into a polesaber.
As for han dying, that was the sad moment of the movie for me, he and fett were always my favorite star wars characters, far moreso than the glowstick twirling force junkies. Smugglers and bounty hunters FTW.
However, I've heard theories that perhaps han isnt actually dead and survives the encounter. Hard to believe, but then again we did see Darth Maul survive getting cut in half and return to confront kenobi, so anything is possible.
