Well to be fair the first two seasons were unprecedented. I feel like there are so many good shows available now that these later seasons are worth your time if this is REALLY your thing. For me sci-fi comedy is a special niche I really enjoy.
It’s gone a bit downhill. I enjoyed season 3 but there are still a few great episodes since. I really liked the last episode, which ironically went against the show’s principle of establishing a backstory.
Took me a while to start watching, and it was great, really great. Then at some point I just got tired with it, whether that's on the show or on me I don't know.
I’ve enjoyed the last 2 seasons of solar opposites more than Rick and Morty. Still a good show though.
