Off the top?

No point in Jon fighting all those battles, saving all those people, being named King, just for him to be sent to the Wall... All because an Unsullied guy wasn't happy, even though said Unsullied guy planned on leaving the island to sail somewhere else, so there was no point listening to him.

No point in Jon being sent to the wall to serve, just to go beyond it to live with the Wildings.

No point having two shit sisters and a brother who seemed to forgot everything you've done for them, just so they can take requests from previous mentioned pointless Unsullied guy who they don't know.

No point Bran being king, since he dips out of meetings early to go spy on shit.

No point in Drogon laying under the snow...

No point going on and on with the massive amount of inconsistencies this season and getting mad, since the show has ended and there's nothing we can do.

Let's just hope the prequels are better.
