Okay, if you make it through the next three and still aren't feeling it, you can give up.
The next three are M. Night Shame-aliens, Meeseeks and Destroys, and Rick Potion #9 (hoooooo, boy).
Each one is brilliant and dark and totally exemplary of the best the show has to offer. These, and the finale, are the core eps of season 1. And then second season totally blows them out of the water in terms of quality.
