Rick Sanchez (Justin Roiland) is a brilliant scientist that has crazy adventures with his grandson, Morty Smith (Justin Roiland) through the entire universe and multiverse. Sometimes join with some other member of the family, like Summer Smith (Spencer Grammer) the teenager sister, Morty's mom, Beth Smith (Sarah Chalke) and his dad, Jerry Smith (Chris Parnell).
This is the plot summary for the entire show. It's an episodic show; every episode is a new adventure, and the continuity is usually brought up sometimes but it doesn't change a lot on the plot. But "Rick and Morty" have something that differentiates the show from others. It has a soul, and it seems to have a message "Nobody exists on purpose, nobody belongs anywhere, everybody's gonna die. Come watch TV". I'm joking with this last part.
"Rick and Morty" is a parody of the sci-fi genre, there's a lot of episodes that are a parody of some sci-fi movie (Anatomy Park-Jurassic Park) or maybe they use some concept of the genre, like travel across the multiverse, making devices that makes dogs smart and able to talk, a love potion, travel to another planet or dimension, or stopping time.
This show has many ideas and they are pretty well developed, the characters are so likeable and funny that you will remember the main characters and probably some episodic characters like the meeseeks.
My favorite and must-to-watch episodes of the season are 1x02 (Lawnmower Dog), 1x05 (Meeseeks and Destroy), 1X06 (Rick Potion #9), 1x08 (Rixty Minutes) and 1x10 (Close Rick-counters of the Rick kind)
This season gets 8 out of 10. Because I totally forget some episodes of the show like 1x09, 1x04 and 1x01.
