I just feel as though there needs to be more of a defined goal right from the start. So far finding Outworlders and freeing the Dragon have been those things, but those are quite vague goals, especially since the dragon isn't communicating with Rimuru anymore. I think that's part of the reason why the show has felt quite aimless so far.
I could wait until the show has finished, but by then there might be stuff I'm far more interested in. I'm already feeling pretty worn out by this season, and I'm playing games instead for now.
