I wholeheartedly agree with you, and I'm a diehard fan. The callbacks and 4th wall stuff is getting a little old, so is Rick being basically immortal. One of the things that was so interesting the first few seasons was that Rick wasn't this invincible god who could do anything and everything. Yes, he was a genius, and got himself out of some jams, but he was also vulnerable. Now it's like there's no tension at all, as he just has an answer for whatever happens and walks between the raindrops.
I thought this episode was pretty decent, as far as the last 3 seasons go. I thought it could've been epic, and had so much more potential. Maybe if it was an hour long premier to flesh out some of the story more. I don't know. It was just all over the place. Morty went back to his original Cronenberg world, but he was only there for a hot minute. Thought they could've done more with a really good idea of them all being transported back to their original realities.
