The Disney Trilogy would be so much better if Po was killed off in the opening scenes of TFA as they originally planned.

Significantly changes the character of Finn: former Storm Trooper that needs to live up to the name of the “most daring pilot” that sacrificed his life to save Finn (and gave him his jacket + droid). A lot of that is lost now that Po’s still around.

Plus sets up Rey, Finn, and Kylo as the 3 main characters. That’s a manageable number.

Instead, The Last Jedi was ruined by too many characters:

Po’s still alive and needs something to do, so construct an elaborate 80s sit-com lack-of-information confrontation with Laura Dern.
Finn needs something to do. Send him on an elaborate Casino Planet plot that does nothing. It could have been just he and Leia in a single plot on the ship. But we couldn’t have Finn on the ship, because Po is already serving that role.
Finn needs someone to do. Introduce another character Rose for some reason. This should have been a love triangle with only the 3 main characters Rey/Finn/Kylo instead. Now that we have so many characters, they’re playing down the Rey/Finn link.
