When it came to this episode, I thought it was pretty good. I noticed that the Cussler had a few similarities with the Titanic. The similarities being a luxury liner, and sunk after striking an iceberg. I would have liked to see more exploration of the shipwreck though, but I didn't expect to see so many different types of marine Pokémon, so I guess it's fair. But what I would really have liked to see was Ash getting Skrelp.
