There isn't anything particularly bad about this game's graphics, but there aren't any areas that really made me stand up and take notice. Everything from the sandy beaches to the jungles and huts come through very clearly and really help to sell the feel of the game, but unless you are sitting there staring at them, the images themselves aren't all that memorable.
Audio is very much in the same boat. Sound effects and music get the job done, but like the graphics, aren't all that noticeable once you shut the game off. At least the game's voicework isn't horrid. There are a few parts that seemed a bit clippy, but overall the work is solid.
