Most underrated animal exhibits

[Pertinax]

Personally I thought the tiger enclosure in PD was mediocre at best, especially considering how much money was likely spend to make the enclosure look impressive.

When I saw this enclosure I was struck mainly by how bare it was. The temple theming is fine but the interior of the enclosure has nothing but grass and maybe a log(?). Bamboo planting plus additional trunks or boulders would help massively to break up the bare feel, not sure why they haven't done this as most(but not all) of their enclosures are more lavish.
