People forget that action and comedy can be smart, and a slice of life oscarbait can be mindless. Oscarbaits tend to nail down oversimplified messages too hard that makes it look like the writers think the audience are dumbasses.
Action and comedies with clever writing and solid character development get a lot of focus or become a "normie" show (that term is getting broader and broader ya special snowflakes) for a reason. They can address political or social topics in an unexpected way that's driven by how the characters deal with them, and shown from multiple viewpoints if it drives the conflict. If it plays a significant role in a character's development you bet your ass it'll be approached intelligently too.
At least in a good amount of action and comedies. There's a good amount of slice of life animes with interesting characters and unusual premises with writing good enough that you forget it's slice of life. You know how it gets pulled off? By having interesting characters. You know what's cursed by a status quo of like four or so archetypes that we've seen a thousand times over and ultimately leaves the characters flat and forgettable? "X but with cute girls" animes. Or, waifu animes.
