Now that I listened to it, isn't that kind of the point? H2O doesn't strike me as something too deep, just something you would put on and enjoy for what it is at face value.
I don't think the point of any album should be zero lasting value. There are tons of albums that aren't deep lyrically or anything else, but you still want to listen to them 20+ times. but if a band is only striving for face value and 3 listens, then they're doing something wrong.
