I really enjoyed the movie. The big complaints I hear are about how it is too much like A New Hope with some Empire thrown in. So? That is a bad thing? Those were the two best movies and this captured the spirit of them.
OMG! A death (planet) star! A hero who lived on a sandy planet! An older gentleman dies! A father reveal!
I saw the three originals in the theater when they came out and this movie did take me back to 1977 again and has me waiting for the next one.
I think all those who say it's A New Hope II wouldn't be happy no matter what. If it was different then they would say it strays too much from the originals or that it really doesn't fit in with what has been established in the past.
