Everyone one was OOC. Rick, Morty, JERRY, Summer. And Beth is becoming dumber and dumber. They're all assholes now. Every single one. Summer bounces from unstoppable to incompetent. Morty doesn't care anymore. The reaction to Jerry from the other characters is inconsistent. Rick continues being dumb-man's genius. Beth is a piece of shit.
What even was the conclusion of that sub-story. Summer is sad because shes been dumped, so she fucks around with Rick's machine and becomes huge. Beth tries to figure out how the machine works. Morty is pissed that now everyone else is doing this shit and Beth is a piece of shit.
Summer runs to her ex, Beth becomes titan too, Morty fucks Summer's ex. What was the point? The next scene nothing happened. They're all normal and back and happy that Rick is back.
Pull the trigger, none of these characters matter.
