I have a feeling this has been presented before, but I couldn't find it and I thought I'd mention it again. For those who advocate the mixed up order of 4-5, 1-3, 6 of the SW films, this site offered a modification of that.

The Machete Order advocates simple dropping Ep. I. This saddens me for a few reasons, as I've grown more fond of TPM recently, and I think it had a character with great potential in Qui-Gon (though he was seriously underutilized). But it makes a lot of sense if a person wanted to watch the SW films for the first time to do 4-5, 2-3, 6.
