Game of thrones season 8 episode 5 trailer

Whoever is following game of thrones this season, may noticed that something is not working right. at least more than it was in the previous seasons. there are 4 episodes behind us and they were not good. the 4th one was the worst in the series (That's what critics say).
With all that said I feel that episode 5 which is gonna rock, at least that's what I feel. I don't really know why as this season didn't show anything that is worth mentioning. Episode 5 is the new nine. This episode has to be good. Otherwise, this entire season belongs in a dumpster.
