Did any of the characters make an intelligent decision?
The only time I can think of is when Rose/Poe/Finn mutiny against purple-hair, but that's understandable because she was so sh!t.
I'll give you examples: Force-ghost Yoda could blow up the Dreadnaught with Snoke on board but decides to blow up the Jedi texts that could help Rey instead. Rose/Finn go on a top-secret mission and immediately decide to park in a no-parking zone.
