I think like 80-90% of their Prequel criticism is valid.

I remember the most contentious point brought up in the reviews (back like a decade ago when there was a lot of discussion about this) was that the plot (to Phantom Menace mostly) is hard to follow, incoherent, or under-explained.

People that disagreed usually reacted by saying something like “What? I understood the plot when I was 10! Why are you so stupid???” or “Is RLM so stupid they can’t understand the plot of a kids movie??” or whatever. Regardless, I agree with the overall point RLM makes regarding this issue.

I do think the famous “character personality test” is a bit over-rated and requires some cherry-picking to really make it work. It’s pretty easy to describe character traits for Qui-Gon, for example, besides just “stern”.
