Grrr! 2- things: the lack of dialouge
The lack of dialogue when Cpt Davidson ios captured by the apes is so frustrationg. Realising that they ALL speak English, surely ANYONE with half a brain would let it be known that YOU are intelligent, can argue a point and explain where you come from?
2nd point: Roths overacting ruined it for me, he was more like a vicious DOG than an ape.
