Despite the odd theme choice, I actually find Toon Lagoon quite impressive. The area is interactive and fun, with photo ops out the wazoo, and I am always impressed by how they manage to make the music flow in the area, with each comic strip getting a few lines in the same song.
Obviously, though, it is the weakest by popular opinion (aside from MAYBE LC, just because it has no rides or IP connections), and suffers from being too water-oriented, especially when immediately next to the premier water ride on the resort.
I would miss TL, but wouldn't be resistant to a potential retheme. My only issue is what to do with the rides currently there? Both are good rides that could be great with new theming and animatronics. I just wish we could airlift entire rides and space them out better through the resort.
