More boring than a real aquarium.
Meh. Very boring story. It's just badly written. I was kind of hoping that Brother and Sister wouldn't get what they wanted at the end, like the attraction was closed or something, and they would have to deal with the fact that other animals are also cool. These kids are just a frigging pain. They're not very likable. I don't really have much to say about it. It basically says that nothing in the aquarium is interesting except the main show. That's what the kids want to see, and anything else that their parents point out to them is boring. They don't care. They just will not shut up about the stupid dolphins and whale. There's no resolution or character development. There's no real point, let alone a message.
The family goes to an aquarium. They look at all the fish. Brother and Sister want to see the whale and the dolphins, respectively, and their parents keep telling them, "Frigging wait. For crying out loud, there are other things here." The cubs just want to see the main attraction, and they go and see it. The end.
It feels like they're trying to make a point, because the cubs keep seeing signs for the main attraction, keep whining about it, and keep getting delayed. There should have been a message here. Perhaps, you don't have enough time to see everything and you don't always get what you want. But no, they got what they wanted.
The best part: The badly-written ending. "The whale and the dolphin made a big splash. The family got all wet. 'Splash!' yelled Honey. They laughed and laughed and laughed." And it just ends right there.
