All this Yoda calling lighting justification talk sounds to me like mental gymnastics 101. Yoda somehow via the force either creating, influencing, directing, etc. the lightning in TLJ just doesn’t sit right with me whatever the reasoning. Pre-ST force ghosts could not affect the physical world. Suddenly in the ST they can directly influence the force back in the real world.
Sorry but I don’t buy it anymore than I bought the ugly Yoda puppet. I also didn’t buy “crazy yoda” as he wasn’t crazy or unhinged in the OT, just a little eccentric and put on a crazy act to either test Luke in TESB or make himself seem harmless while checking out who this stranger was that just crash landed in his backyard.
Yoda was joking around even when he was dying in ROTJ. He always had a jovial side. Something the PT completely got rid of with grumpy frowning Yoda. TLJ Yoda was the same Yoda we see in the OT.
And OT Force ghosts could interact physically with the real world, so why can’t they also use the force? Or is it just because it’s been introduced in the ST that’s the problem?
