I liked it, quite a lot – and will probably go to see it again.
Yes, the dialog was atrocious at times, but the pacing of the film was
excellent, and it was the film I’ve wanted it to be : suitably
dark, and generally depressing all round. I kind of hoped to see a bit
more of Vader as the character we know in episdodes IV-VI, but in
general he was as evil as he should have been, even without the
breathing aparatus.

As a closing thought, I think that if Lucas had done the first two
films (Ep. I & II) with a more restrictive certificate like this one,
they mightn’t have been the let-downs they were. Perhaps I just have to
wait for the director’s 40th anniversary cut (or somesuch).
