If you're travelling with kids, this might be worth going to. Exhibits are okay. Drawback is that most of the show commentators speak in Thai. The 5D movie was really nice.
I'd say this is comparable to Manila Ocean Park. (as a point of reference: I don't like Hong Kong's Ocean Park. That's too rides-centric). I still think Manila Ocean Park is better. It definitely has the best jellyfish exhibit of the three.
