Mantaflow fluids are rectangular and not liquid looking

My data looks very good within blender. My mesh however, appears like a pure rectangular glob. As you can see on the left, the look im trying to achieve, my liquids look NOTHING like that and I cannot figure out why!

How does one get their fluids to look like fluids and not a rectangular block? (Also yes, the domain is much bigger than the flow object, my scene is an identical copy to his minus fluid simulation.
