Please do try! I have original VHS versions of both the theatrical release (hard to find!) and subsequent director's cut which became the mainstream. Now you can find them all on DVD. I recommend watching the director's cut, then the original theatrical release. Changes aside from the voice over are really subtle, but important! If you want to go for completeness, watch the final cut as well.
Maybe I'm just a hardcore fan, but I did that with my girlfriend while explaining all the differences and she really liked it.
