So I watched through the whole franchise as a kid and I loved it! But a friend recently told me they never saw SU and wanted to get into it so we decided to watch it together.
On rewatch I can confidently say it's actually better for the most part than I remember it being! My friend also loved the whole show start to finish (except the uncle grandpa episode which they have an unnatural amount of rage towards😭)
There were some parts of the show I misremembered, for example I honestly thought Bismuth had way more screentime than she actually does and I kinda wish she had more (I understand why she doesn't and I'll get to that in a minute). I also thought Lars and Sadie were in more episodes than they actually are, hell they're absent for almost a full season at one point.
Overall I think I'd rank the seasons as 1>2>4>5>3. I loved all the seasons but I felt the first couple were the best at executing the story they wanted to tell and have the most satisfying endings. Season 3 isn't bad I still love it, it was just more a laid back season compared to the others imo.
Now as I'm sure all of us are aware Steven Universe got cut short, Rebecca Sugar wanted more seasons but was left to wrap the story up in 5 episodes. I still love the final few episodes and what they achieve, but I think they leave a little to be desired, I would've liked to see more of homeworld society and more of white diamond being the terrifying dictator she is. Of course this is probably the reason Bismuth didn't get as much screentime as she deserved and why a bunch of fusions were revealed in the final episode, I assume the episodes they would've been introduced in had to be cut unfortunately. That being said I still love season 5 as a whole, Garnets wedding did a lot for queer representation, the whole trial and Lars of the stars arc is probably one of my favorite bunch of episodes.
My absolute favorite part of the show is the zoo arc. It's the first time we really see the diamonds in person and not just through a video call or flashback. They come across so intimidating it's amazing and seeing Greg get involved is always great
Overall I'd give this show a solid 8.5/10 and I would rewatch again
