Agree to a degree, mainly because I knew what was going to happen and nothing new was going to surprise/disappoint me. After reading the IMDb trivia after watching it the first time (a tradition I do after nearly every film I watch now) and random news articles, it was nice to notice some of the quirky things I missed first time/didn't know (ie Daniel Craig.)
However I only went to watch it a second time because I had to take the missus with me, who had been most displeased that I had been to see it without her - even though I hadn't exactly said I would go with her in the first place. The things I do for love.
They're not really though.
Poe: Best Pilot. No other information given. Gives jacket away.
Finn: Bred in a lab. Complete pussy. Gets free jacket.
Rey: Freelance young Anakin Skywalker (in the sense that she messes with fucked up old machinery). Yes she has things unexplained, but things shrouded in mystery do not equal "complex".
Chewie: Raaaarrrghh.
Han Solo: Han Solo.
Princess General Leia: Doing the same thing even though it appeared to be abolished 30-or-whatever years ago - effectively pissing on the whole efforts of the original trilogy.
