I really enjoyed it and will likely go see it again. The 4K screen resolution is great without the overpriced hype of 3D (totally not worth the extra $$$ IMHO). Anyway I thought that a lot of the "borrowed" items (and yes I did have a few "hmm where have I seen this before" moments) were deliberate choices to (1) give a nod to the ORIGINAL trilogy (and put distance between Episodes I-III and the new films) and (2) subtly say, "okay we're picking up and acknowledging the good elements of IV, V and VI - that's where we're starting and we're going to go our own direction from here".
The reviews have overwhelmingly been positive and I can see why. JJ Abrams didn't screw this one up and realized he wouldn't make everyone happy so he made 99% of people happy by giving them something that they could latch onto and get comfortable with the SW series by again (I think I can watch Ep. VIII without wondering how JJ Abrams will eff it up now, which is comforting).
I really enjoyed it. The SFX actually served the plot and not the other way around, which is refreshing. It underscores just how badly Lucas lost his way. I'm looking forward to the next episodes! Rey kicks butt (yes I know - "Lara Croft" ripoff but I don't care - tough, independent, attractive, smart and a British accent? Where do I send my marriage proposal?).
. I wonder who her mother is - I have a pretty good idea who the father is...
