antifascist themes? 
environmental preservation subtext? 
coming of age story where characters actually act their age? 
che guevara character that monologues about what the events mean? 
FLYING SURFING MECHA? 
banger fucking soundtrack? 
ok downsides are - the first 10 episodes are pretty rough honestly aside from the first two. weird 2000s anime tropes and some anime weirdness with women but this does develop out well as the characters do. some of the characters are strange stereotypic designs (black guy who djs and wears basketball shirt) but the characters absolutely are not standard tropes in their own way.
either way i recommend a watch and try not to cringe too much during the first arc

Eureka7 was the shit tho. Like futuristic antifa vanlife.
the eng VO for renton just makes him sound like a fuckin babby
the jp VO is way better at this, he seems a lot less bratty (he is literally a child though)
Ah word, I'm trying to remember if I watched it on adult swim or if I was into subs by then.
I wanna say I grabbed it off animesuki but it was a long time ago.
