Adult animation has a funny way of outliving its first home. Shows that seemed to end quietly on one platform often find a bigger, louder audience somewhere else, and that is exactly what happened to the alien family at the heart of Solar Opposites. Their final season is now reaching viewers who discovered the series late, and for many of them it will feel brand new.
The appeal has always been the contrast. On the surface it is a cartoon about stranded aliens trying to pass as an ordinary suburban household, complete with ray guns, mutant pets and badly judged science experiments. Underneath, it is a surprisingly warm comedy about families who drive each other mad and still stick together. The voice cast gives each character a distinct rhythm, and the jokes land fast enough that a rewatch usually reveals gags you missed the first time.
Then there is the strange little world hidden inside a bedroom wall, a side story that grew into one of the most inventive parts of the show. It has its own rulers, rebels and tragedies, and following it to the end is reason enough to finish the series. Not everyone agreed with how it all wrapped up, but debates about finales are a sign that people cared.
For newcomers, it is also an easy show to start. Each episode stands on its own well enough, so you can dip in without a long commitment.
If you want to know when the episodes landed, how the earlier seasons performed and whether there is any hope of a return, this Solar Opposites farewell guide covers the details.
Our directory pick: this is ideal for short evenings when you want something silly but clever. Watch a couple of episodes, then decide whether you are ready to say goodbye to the Shlorpians for good.
