Thx for the link msycamore:
Deja vu... similar thread here: http://originaltrilogy.com/forum/topic.cfm/Since-when-did-ROTJ-become-less-highly-regarded-than-even-Episodes-II-or-III/topic/14909/
Will check it out.
I guess by "technicaly a better film" I mean that ESB runs smooth from start to finish, flawless at every point. Where as ROTJ has highs and some lows. But the highs are so very, very high. i.e.
Sarlac pit / Speeder chase / Greatest space battle ever commited to celuloid / Throne room sequence
ESB has no momments to touch the exhileration of the first 3 of these sequences. Vader and Luke in cloud city is on a par with the end of ROTJ though.
Plus ROTJ introduces us to great characters like Jabba and The Emperor who are easily as good as ESB new characters (Lando and Boba).
