Escape from the Planet of the Apes (1971)
Ah, I see they've lightened up the tone.... HOLY **** WHAT THE ****!?!?!!??!!?
This very much feels like the natural route to take the franchise, putting Zira and Cornelius in the shoes of Taylor. It's a bit dorky in it's Star Trek 4ness, but I appreciate the sincerity.
The villain, Dr. Hasslein looks exactly like my old boss, who was probably also a baby murdering ****.
Conquest of the Planet of the Apes (1972)
I liked this one quite a bit. I like that despite Zira and Cornelius' warnings, humans A: still made slaves of the apes and B: even without nuclear war they nearly got their asses nearly extinct anyway. Humans can be that stupid in reality too.
I was really surprised J. Lee Thompson's name in the opening credits, and it shows. In spite of a low budget (There's like two locations in the entire film), there's a level of panache that's been missing since the first. Especially the action scenes, which he's always been good with.
On an objective level, I'd have to call this the best of the sequels, but the bat**** insanity of Beneath still makes it my favourite.
Battle for the Planet of the Apes (1973)
It was interesting to go back to the post apocalyptic style of the first and touch on the bomb cult again. But by this point the series had totally ran out of steam. I suppose the film makers knew this too and probably made it to give the series a happy ending.
