There are some zoos that focus on animal rehabilitation, saving endangered species and public education. As long as the animals in those facilities are well cared for and kept in a pseudo-natural environment then I think they serve a positive function.
However, I think those facilities are in the minority of zoos around the world. Keeping large, intelligent, social animals like Orca in a marine park smacks of animal cruelty for the sake of entertainment and profit.
