Sorry, unless you're an angsty teen, you weren't meant to relate to emo-vader, er, Kylo Ren. You were meant to relate to Han Solo. But you'd only relate if you're a parent. If not, then I guess there's always Traitor-guy. Yes the new episode is derivative. That's because it is how epics are told. It will diverge on the next two episodes from the original trilogy, unless Disney gets scared... that would be a huge disappointment...
