Hmm. I liked the ending (the videos, that is). I felt the game wasn't about Jenson or Reed at all. It was about the future of humanity regarding augmentation, and maybe even more than that (the Illuminati), and in that regard, the ending gives you some good closure. Plus, the videos were pretty well made, with a nice soundtrack.
What disappointed me was the idiotic final level, and the wtf-is-this-why-do-I-have-to-kill-the-three-girls boss fight. Could that ass Darrow really not have thought of a way to get augmentations recalled without killing everyone? Does he really think even his extreme actions will stop the progress of humanity for more than a temporary pause? It seemed extremely forced for a climax, and gameplay wise, fighting civilians armed with their fists, after fighting through installation after heavily guarded installation, is a joke.
I also thought saving Malik was the highlight of the game. Other than Sarif, who I grudgingly respected, and I guess maybe Pritchard, Malik was the only person I liked, and I felt she might just have been the only straight-up good human being in the game. I managed to take out all the Belltower assholes non-lethally in one try, but if it came to breaking out my fully modded combat rifle, I would gladly have done it.
