I finally got to see it a few days ago. It's bizarre that I did not manage to see it earlier, since I have been eagerly awaiting this movie since the 90's (and it even starred Han Solo!) but real life prevents me from indulging immediately in every movie I want to see.
Anyway, I liked it. Of course it wasn't nearly as good as the book, but I never expected it to be. Despite some big changes that others have pointed out (like the FTL traveling and the condensed period of training time) it actually followed the book more closely than I was expecting. It's a shame it didn't do better at the box office, because I thought the filmmakers did well.
