How can you not like humanized monkeys??
Yeah, the plot is weak and the human actors don't have much to work with, but those monkeys are freakin HILARIOUS! I love the part where the goons come to the apartment to take the apes away in a cage, and one of them ends up getting into a conversation about a book with Poppy!
Going Ape didn't deserve an Academy Award, but its just fun as hell to watch (especially since its not on DVD, and only lands on TV like once every 5 years)
