Well, I also just came back from watching Rise of Planet of the Apes and I guess I must have that ability to turn my brain off, because I seriously enjoyed it XD
Isn't that weird, me, the guy who's always bitching the first chance he gets, I really liked the movie XD Okay, I will admit that all of To's complaints are absolutely true, but I'll try my best to explain some of them.
-Caesar was incredibly intelligent, so he had probably heard Franco's character talk about the effect of what was in the canisters (As we've seen, he likes to talk to himself a lot)
-As for why the hell Franco kept those at home, I can only speculate. Maybe he was a mess after losing two people (The term 'people' is used loosely) he loved at once and because of something he created. Maybe he was planning on doing more illegal testing on people. I dunno.
-Tom Felton tried to get Caesar back in his cage with the tazer because he's an ego-swollen kid that needed to prove something to himself. He wanted to look like a tough guy and convince himself that he was at least better than a monkey. I'm fairly sure a lot of people his age would have done the same thing.
-I have no bloody idea how he got out of his cage. Maybe the monkeys didn't tie him up well enough, but, again this is just speculation.
-Optimus Primal (Wasn't he just awesome?) might actually have seen a car accident, before. They established that some monkeys have been in the field of testing for a really long time and maybe the big gorilla had also been tested on. Maybe he was riding in a transportation truck and saw a car accident similar to that one through his little window. Maybe he thought the car was an animal and, after all, if you throw something heavy on a living thing, it'll hurt it.
-I don't know, for the 3 employees for the Ape Prison. Budget Cuts? Then again, how many people could you possibly need working there, when the employees basically never come in contact with the monkeys?
So yeah, the movie had undeniable flaws, but I still really liked it. There was a very pleasant camaraderie between the apes, the special effects were very convincing (Especially since all the apes were pretty much CGI) and nearly all of the characters were enjoyable. Unlike To, I'd recommend it.
Though I totally respect To's opinion, much like I'm sure he respects mine :p
