If you’re going to nitpick grammar, you shouldn’t say “somehow tied.” I suspect you mean “somewhat tied.” And if we’re going to go that far it really should be “somewhat tied together.”
Yes, sorry, I’m not a native speaker.
And yes, the trilogies could have been tied better but after TFA and TLJ came out, the prequels’ problems appear to me as insignificant, compared to the ones of the sequels.
Anyway, this list of things are just my two cents. I know that some ideas are very difficult to realise but still some of them could be of interest to some fan editor. Just not stop reading at my made-up-in-two-seconds nickname. 😛
