One of the most consistent shows ever, obviously due it only having 18 episodes, but every episode was genuinely amazing and it's obviously a true tragedy that it got cancelled. The cast was incredible, every character was relatable and the writing was so good, especially when it hit some serious tones.
It also holds up insanely well compared to when I used to watch it as a kid and is definitely one of the best sitcom/comfort/coming of age shows ever.
Anyways don't be sad that it's over, be happy that it happened.
