Maybe it's just that it's difficult to maintain interest for this long in a series. Three films is a challenge, five almost an impossibility. Sure, by now we get it. There's a good element and a bad. Here's we've got the gorillas and the "underground' humans taking on the bad element, and there's just not much to be done. But as one knows or feels throughout, you know it's the humans who are the worst element of all, for they are the one's that ultimately end civilization. There's also and issue here with budget. This has more of a feel of a college film than a successful franchise film. Fox was trying to cut corners to extend profits, short-changing viewers in return. Ah, but isn't that just like those evil humans?
