The movie stands the penultimate test for a Star Wars movie:
That is, you can watch it more than ten times, and still enjoy it! (Of course the ultimate test is whether you can enjoy it over 100 times, but I'm going to wait a few more years to bring up that question.)
I admit, I've been home sick this week, and as I've been in a mood for mental comfort food I'm now watching it again for the 3rd time. It's great!
