Oy, i tell you, i love star wars, the OT is better, Jar Jar is annoying, but i'm not such a die hard fan that i'd say, "No! The SE's are not allowed in this house!" or "The PT is forbidden". I'm sry, but people would look at you and think you're very...oh, whats the word? I dunno, some word that makes you sound weird. I guess Weird works.
One thing i do agree, i think you should start with A Hew Hope first so that the revelation that Vader is Luke's father is that more climatic when you first watch it.
