It is interesting, something to try if you have some time to explore it and have any interest in how they manage the animals in the park, or what sort of research/environmental-impact studies are going on there, or things of that nature.
(Sorry for the bad pun at the end of that last sentence.)
There is a petting zoo, and interactive exhibits, things of that sort. It all has a conservation theme, but it isn't dramatic or preachy.
We use it sometimes to kill time while waiting for Kilimanjaro to calm down or for fastpass times to roll around.
