One thing I'm hoping Abrams "replicates" from the new hope, is the slight peppering of humor throughout the film. Think about the little bits of humor spread lightly here and there: between R2 & C3, between Han and Chewie, Leia and Han, and I'm sure other relationships I can't think of at the moment. One fear of mine (hopefully I'm worrying for nothing) is that Abrams makes this a totally serious film throughout. Sure it will probably be awesome even if that were the case, but if he takes a cue from his predecessor, I think adding a little humor (sparingly) here and there will make it that much better.
