As a kid I kind of disliked this movie ...
I thought it was good and pretty entertaining, better than Jedi, but both it and Jedi were big steps down from and less enjoyable than the first film. I thought it was a little too dark ... it felt like the whole movie was either Luke failing or the good guys otherwise either getting defeated or just barely escaping.
As an adult I still think ANH is better but not by much. That it is so dark, almost unrelentingly, is impressive but still somewhat unpleasant and even somewhat forced.
