Meh, he's actually been getting more mature as the show goes on.
Seriously, the first episode of the show was about him thinking his favorite fucking ice-cream was the key to his magic powers. In the latest episodes he>Turned himself in and took the blame for his mother's crimes to spare his friends.>Spent the fight on the ship focusing on figuring out how he and everyone else was going to get back to Earth.>And led an escape from their prison on the Gem Homeworld.
Seriously, I get it. But he's gotten a lot better. It's like night and day if you compare them.
The show also turned the second worst townie character into the best character of the show.
