That’s an impressive and very insightful OP, thanks for your dedication!

I got introduced to Star Wars franchise in the chronological order and in Latin Spanish dub. That always influenced my view on the prequels on 2 main aspects:

Much like EddieDean said, much of the character introductions, worldbuilding and perceived coincidences seem far less contrived when the trilogy is viewed as the actual first set of films instead of prequels. On the other hand, TPM doesn’t delve that much into what the Force is, and it’s unfortunate the earliest explanation for it involves the midichlorians.
Some of the dialogues and particularly most of the line delivery and voices are far less obnoxious in the dub (the improvement is pretty noticeable with Hayden Christensen’s dialogue in the later two films). So for me the dialogue issues were hardly relevant until I saw the movies in their original language.

This influenced on me never having strong feelings against the prequel trilogy and despite their flaws I consider them enjoyable movies, of course never reaching the OT’s level.

I’d probably post a more thorough review when I have more time, but here are a couple of abridged thoughts about TPM.

I do find Jar Jar annoying, but not irredeemably hateful. I’d be interested in a fan-edit that redubs him. On the other hand I admit to liking Boss Nass in a guilty pleasure way.
Overall this film looks much more naturalistic and pleasant to the eye than the other prequels.
I do think TPM benefits from going immediatly from meeting Jar Jar to the arrival on Theed, but I’d hate to lose the visuals of Otoh Gunga. At least the Submarine breaking down and the second pair of fish could be excised seamlessly.
I’ve never had problems with the droid dialogue either on this film, the later prequels or TCW. I find them funny.
The identity of Darth Sidious should be better concealed in his holographic appearances, like having his face or voice distorted. We don’t need the explicit Senate references or anything that links him too soon to Palpatine other than the funeral shot. This would benefit the audience for both the chronological and release viewing orders.
Maul was severely underused, but I don’t see a way to remedy this sticking only to TPM.
