It's neat, speaking as someone with no prior familiarity with the originals. I'd say most everything about it is competent enough, and I'm hoping future seasons will be even better as the show rises from its clear growing pains.
As far as shows spilling from Spring into Summer go, I'll be still keeping up with Lupin III: Part 5, My Hero Academia S3, and Steins;Gate 0, just to mention those for the sake of it. For shows starting this season though:
I've been watching FLCL Progressive as well, though as someone who never...
Not just my first anime, but I think it may have been the first TV show I ever watched, or at least that I can even remember. Tons of fond memories and surprisingly still holds up great today.
"All of them" is the easy answer, but I guess for specifics, the ones I've had the most negative experiences with are probably the ones for RWBY (really Rooster Teeth shows in general but mostly for RWBY) and, mostly in recent years, Star Wars.
Is it really? I've only just finished the Yorknew City arc, but everyone around me keeps saying that the Chimera Ant arc practically blows the rest of the arcs out of the water.
My least favorite three would have to be Sword Art Online, Angel Beats!, and FLCL. Recently I finished Black Bullet and No Game No Life and I wasn't too fond of those either.
