What’s Ahead?

I didn't mind the casino planet arc. I felt it had an important message. Rose and Finn come up with a crazy idea (the first order is able to track them through lightspeed but for some reason they only do it from one ship. What sense does that make? Only a pretty stupid military commander wouldn't have backups in case of malfunction, sabotage, or whatever). Then they sneak off, get arrested, and decide to trust some random guy. That they met in a prison cell. They make it on to the enemy ship but get caught because the enemy wasn't a bunch of morons. As a result, the First Order corrects and oversight (not monitoring for smaller ships) and is able to massacre a large part of the resistance.
In other words, Finn, "we'll use the force" proves that even if the force is on your side, stupidity will not win the day.
Also, I thought Finns suicide run at the cannon was at least partially out of guilt for all the deaths he caused with his idiotic and shortsighted plan.
