Funny enough, I stopped watching Big City Greens sometime last year. It wasn't bad, just didn't hold my interest enough (though Tilly remains a top tier daughteru).
Amphibia doesn't need to be unique or groundbreaking, but it's been great at nearly everything it accomplishes. Does it have the greatest depiction of country folk in animation history? Probably not. But it does has Hop Pop, so it gets an A in that department.
