@drill um, why exactly? This looks like a very nice little project that will definitely modernize what has been a part of the zoo that has been in a state of despair for a while now. Sure, I wish that a new animal exhibit would have taken the space, but it still looks quite good on its own.
So...underwhelming would be my first word choice in this situation. Something had to be done to replace the outdated mock-rock 'Baboon Blob Island' but the upcoming Hamill Family Nature Plaza would definitely not have been my first choice. A prime piece of land that would have been a substantial area for a new animal exhibit is going to be turned into a pleasant but mediocre addition to the zoo. Brookfield Zoo continues to slowly deteriorate...
Brookfield Zoo deteriorates on the macro, but not in the micro. No expansions, but many awesome rare additions like Texas blind salamander, Chinese giant salamander, and others.
