I actually think Harry Potter was a good addition to IoA. Although I hate what they did with Dueling Dragons and its queue, the land itself added one of the best modern dark rides and arguably set a new standard for immersive environments at Universal. That being said, I have been to both IoA and TDS and agree that the latter is a far superior theme park. Hogsmeade, Lost Continent, and Port of Entry aside, the theming at IoA is nowhere close to the scale and level of detail found at TDS. In fact, parts of the park like Marvel Super Hero Island and Toon Lagoon look downright cheap and tacky with their abundance of cardboard cutouts.
